Arc-Eye Hawkfish Death
2 days ago I got a baby arc-eye hawk for my 10g tank, the plan being to let him grow a little before adding him as the final member of my 90g. He was doing great, swimming healthy, eating well, breathing fine, and seemed perfectly happy. This morning, the water was cloudy and I figured that the tank was starting to cycle despite having added some live rock from the 90g to avoid any ammonia buildup. Anyways, the poor little guy ended up dying and I can't figure out why. Here are the parameters...
Nitrates: 0-5 Nitrites: 0 Ammonia: .25-.50 pH: 7.9 Temperature: 77 degrees (F) Specific Gravity: 1.024 The only cause I could think of that could cloud the water (the ammonia levels being too low to kill a hawkfish) was the low pH or possibly something from the bleached corals. A friend had bought some bleached coral in the 90s and since he switched over to live rock, it had been sitting in his basement. I rinsed off some pieces and put them in the 10g, I don't know how that could harm a hardy hawkfish but it's possible.

if it is precipitation, are there any steps I can take so that I can use the bleached coral without it killing my fish ? The coral used to be in a big tank and it didn't cause any problems.

The tank was indeed most likely starting to cycle but I didn't think .25 ammonia levels would kill a fish as resilient as a hawkfish, .25 was the lowest increment besides 0 on the test kit. Plus, I figured that adding the live rock to the tank would ease the cycling process but apparently not.

but remember that a fish that has gone from collection to wholesaler to LFS or e-tailer to your tank is probably super-stressed and at its most fragile. new fish need the best conditions you can provide. just by making it alive to the fish store, they have showed how tough they are - the losses of collected fish are very high. new fish need the most TLC. |
