DAYS 100-101

I told myself I must post about this before I forget about it.

When I first re-started reefing in January 13, I noticed there was quite a bit of small, white creatures, presumably copepods, that were crawling over my tank. However, I realized that I stopped seeing them altogether recently. I wonder if my current tank parameters are non-conducive for them to survive.

On a different note, I would usually look at the tank inhabitants in tank 1 and count the number of Sexy Shrimps in it to check if all 10 that I bought are still around. I would always heaved a sigh of relief when all of them are accounted for. However, just 2 days ago, I counted only 8 Sexy Shrimps and wondered if the remaining 2 were hiding behind the rock works. Yesterday, I found it very strange to spot only 1 shrimp and this morning even the only one was completely missing. 

I also found the white branched Goniopora either dead or dying. The typical tentacles didn't extend beyond the skeleton but looked as if they have receded almost completely.

While checking out the tank for any trace of the Sexy Shrimps, to my horror I spotted 2 small crabs. I initially thought that something must be eating them and I seriously wonder then if it was these crabs. How else can anyone explain the sudden disappearance of the Sexies after I had all 10 of them with me for 3 months now? I must start to set some traps for these crabs soon before I decide to purchase and add new Sexy Shrimps.

By the way, I added 2 gobies to tank 1 recently but I have not seen the Neon Goby ever since it was introduced. I feared it is dead. At least I could see the Red Spotted Goby hiding behind the rock works but I too am worried if it would be preyed upon by the crabs.

As for tank 2, there were a number of additions. The second seahorse was found to be dead when I came home from work. The Neon and Yellow Gobies got along fine initially when they were sharing the same container but I now noticed the Neon Goby has been chasing the Yellow Goby around.

The red Coco-Worm and the Tridacna maxima clam are simply amazing! The branched Gonipora has not opened up properly yet and I brought back the Chilli Coral and the branched Candy Cane from the office today. Unfortunately the Sympodium in this tank sort of melted away completely.

All in all, it was both a sad yet exciting day that saw the disappearance or death of some but addition of others

 

THREE MONTHS

Finally, this is the update at the end of the 3rd month. Let me start off with a photo of what I thought was the corpse of the blue hermit crab that I found in my 1.5 feet tank yesterday. Thankfully, it was just a moult but it sure fooled me until I saw the real hermit crab moving.

Next is the full tank shot (fts) of the 1.5 feet tank showing the amended scape yesterday.

Then it is back to the fts photos, of the 2 tanks, taken just a while earlier. Clearly, there is still a lot of room for changes and improvement and that would happen in this 4th month. Until then, this is the most updated information on the 2 tanks:

Tank 1 (1 ft cube - 27 litres)
This tank had a brown oily film about 2 weeks back and I had to scoop it out during 3 water changes. I suspect this had something to do with the freeze dried Cyclop-Eeze that I fed in copious amounts to the tank because of the Sun Corals. Since I was caught up with other stuff and didn't have time to feed the Sun Corals individually, I realized the oil slick is gone although Sunny the orange Sun Coral doesn't look too happy. I am not sure if the water parameters are good but when I tested for phosphates with the Salifert test box about a week back, it registered 0 although I am still skeptical about it.

On a separate note, I am amazed that there are still 10 Sexy Shrimps around but I lost a brown Xenia and Yellow Polyps and I have a feeling that they may have something to do with it. I bought a grey Xenia recently but just two days in, I realized there were less clumps on the rock and had to transfer the rock over to tank 2. Again I am unsure if the shrimps are the culprits because I haven't been feeding them Mysis Shrimps.

I also observed that the new crown that Coco the Coco-Worm grew seemed to take on a more uniform pinkish crown instead of alternating strips of red and white before the two crowns were shed. I wonder what is the cause of this?

Overall, I am quite happy that the tank is quite stable and the fishes, invertebrates and macroalgae include:

• 1 Clown Fish (Candy)
• 1 Hector's Goby (Hector)
• 1 Six Line Wrasse (Wendy)
• 1 Diagonal Bar Goby paired with 1 red and white Pistol Shrimp
• 1 Cleaner Skunk Shrimp (Chris)
• 1 Fire Shrimp
• 10 Sexy Shrimps
• 1 Pom Pom Crab (Penelope)
• 3 Turbo Snails
• 2 Nassarius Snails
• 1 small Yellow Cucumber
• 1 Coco-worm
• 3 big and 2 small (yellow and red) Feather Duster Worms
• 3 pieces of Green Star Polyps
• 1 orange Sun Coral
• 1 pink Sun Coral
• 1 branched Sun Coral
• 1 Stick/Tree Coral (transferred to 1.5 feet tank)
• 2 frags of green Palm Tree Coral
• 1 frag of orange Palm Tree Coral
• 1 branched Goniopora
• 1 fluorescent Goniopora with white eye (with a bubble algae)
• 1 fluorescent Goniopora with pink eye
• 0 Candy Cane Coral (remaining 1 was brought to the office to make space here)
• 1 pink Cauliflower Tree Coral (1 clump moved to the rock formerly with Xenia)
• 1 plate of brown Daisy Polyps
• 1 plate of red Actinodiscus mushrooms
• 1 plate of blue Actinodiscus mushrooms
• 1 plate of Ricordea mushrooms
• 1 branch of Rhodactis mushrooms
• 1 orange Ricordea yuma mushroom
• 2 frags of green Zoanthus (5 small plugs, 1 medium plug and 2 plates transferred to 1.5 feet tank) 
• 1 Mushroom Finger Coral
• 1 Acropora Coral
• 1 unknown coral (not sure if it is Sympodium) with a small piece that broke off and it is still not opened up yet
• 1 rock of red bamboo macroalgae, 1 plate of red bubble macroalgae, 1 plate of red wavy macroalgae and 2 clumps of red branched macroalgae

The casualties are:

• 1 Red Spotted Goby (Renee) - committed suicide by jumping out of the tank when I was away in Taiwan
• 1 Fire Shrimp (Felicia) - disappeared after I came back from Taiwan
• 1 Xenia (presumably eaten by Sexy Shrimps)
• 1 rock of Yellow Polyps (it just slowly disappeared even though I fed it occasionally with Mysis Shrimps while the one in the office which is unfed is still growing)

The technical information is as follows:

• 1 Ocean Free Super Hang-On Filter 2
• 1 Atman HF-0600 hang on back filter
• 1 Green Element 3W LED light (4 white, 2 blue)
• 1 Beamworks LED light (31 white, 2 blue) - just a supplement for viewing
• 1 Tunze Osmolator Nano

Tank 2 (1.5 feet cube - 56 litres)

In comparison to tank 1, I am kind of disappointed with this newly setup tank. It is up for nearly 2 weeks now and the inhabitants are not happy and are not really feeding. Diatoms are appearing everywhere, on the glass and sand. Just the other day, I was sad to find 2 dead Cleaner Skunk Shrimps and a dead Tree Coral. One was actually carrying eggs. When I touched the water, it was so warm. I dipped my hand into tank 1 and surprisingly, the water was cooler. I immediately turned off the skimmer because I was worried the running submerged skimmer pump might have contributed to the heat. I guess I need to do something about this before adding any more shrimps.

These two days I also had to clear the carcasses of 2 dead Six Line Wrasses, which were absolutely gorgeous when I bought them. The remaining 3 Tigertail seahorses are very emanciated and I suspect their ends are near. They have taken on a pale yellow look but I could still make out their bony exoskeleton and their heads looked brown as if diatoms were growing on them. I do know that they can get infection easily in warm waters.

I have 2 clumps of Caulerpa (a feather and a bubble) and because of that, alternated the turning on of two sets of lights in my bid to prevent them going sexual. However, I am not sure if this is a permanent solution. The bubble is looking kind of strange now and if it does die on me, I may not grow anymore Caulerpa in the tank. Anyway, I doubt having the lights on almost 247 is the cause of the high water temperature.

A plate of Zoanthus in this tank and a Goniopora in tank 1 were purchased from Go Octopus and both are sprouting bubble algae. I have to find some means to remove the bubble algae sometime. By the way, all the Zoas have opened buttons here. So I suppose the Sexy Shrimps were the cause of them not opening up in tank 1 previously.

To end this post, here is the list of fishes, invertebrates etc:

• 3 Tigertail seahorses
• 3 Banded Pipefish
• 1 Yellow Wrasse
• 9 Turbo snails
• 2 Nassarius snails
• 1 electric blue Hermit Crab (meant for the office tank)
• 1 big and 1 small (yellow) Feather Duster Worm
• 1 salmon Tree Coral
• 1 Stick/Tree Coral (lost its fluorescence)
• 1 plate of grey Xenia with a sponge/tunicate
• 1 rock, 2 plates and 6 plugs of Zoanthus
• 1 rock of Green Star Polyps (not opened yet)
• 2 red mushrooms
• 2 green Ricordea mushrooms
• 1 purple Rhodactis mushroom (from office tank)
• 2 frags of orange Palm Tree Corals
• 1 red Bamboo and 1 red Bubble macroalgae

The casualties are:

• 2 Cleaner Skunk Shrimps
• 2 Six Line Wrasses
• 1 Tree Coral

The technical details are:

• Ocean Free Super Hang-On Filter 3
• Easy Aqua Ex500 External Filter
• Tunze 9004 skimmer
• 40 cm Green Element LED light (7 white, 3 blue)
• 40 cm AquaZonic T5 lights (2 tubes of 14W)

DAYS 79-81

I wasn't very productive in this month's postings but there were so much changes that happened to the tank. I just made some purchases these few days and this scape is no longer relevant.

I will post the updated photos soon  but the new addition was the Acropora (when I purchased it, the right branches were already bleached and dead).

Separately, I couldn't resist buying 4 Tigertail Seahorses which I saw at Wong Loy Kee. They were transferred to a new 1.5 feet cube tank. Unfortunately, they have hardly eaten and from the sunken exoskeleton I could tell that they were starving for a long time in the shop, even before I went on the Taiwan trip. When I went back to feedback to the owner yesterday that they were not eating, he merely shrugged and said they should be eating. With such irresponsible behaviour, no wonder the authorities restrict the sale of seahorses. I already bought the Seachem Garlic Guard and Entice and soaked the Mysis Shrimps in it but they were still not feeding. At this rate, they would die soon. From this bad experience, I am quite sure that they are wild caught ones and I wonder if it is feasible to release them at sea than to see them die under me.
