All my fish are dead
 

I got up this morning only to find all my fish dead :cry: . I don't know what happened? I turned out the lights last nigh at ten, Went down to turn them on this morning at six and they were all dead. My corals are fine though. No power went out, temp is fine and water quality looks good. The only fish to survive was a damsel, sleeper goby, spotted watchman, one cleaner shrimp (not looking good) and both my starfish. The sleeper goby looks like he has some red by his gills and on his fins. But he seems to be ok for now. I lost my tangs, the rest of my damsels and clown fish. I'm so ****ed of right now :evil: . How could this happen? I moved two weeks ago, but the fish haven't shown one sign of distress. I kept them in their old tank water in a 33 and half the live rock. In alll honesty, they were actuall doing better. I just don't get it :confused: . Lucky for me I gave all my SPS and LPS corals to someone to look after. I kept my softies and leathers and their fine. All my crabs and snails seem to be intact. The worse part is that I planned on moving them into the 72 today. Should be much easier now (not funny) :sad: .

I think I may have assisted in the death of my fish, but I'm hoping someone can tell me I'm wrong. I went to start pulling the dead fish out of the tank, when I noticed a piece of liverock had fallen infront of the powerhead blocking its flow. Yesterday when I was cleaning the garage I had to slide the tank over about a foot. The rock must have fallen then. At night my protein skimmer goes off for 6hrs. Thats when the kalk drip, phyto plankton and othe goodies go in the tank. It also would have been the only thing providing circulation :frown: . Someone please tell me I'm wrong.

Did any of the dead fish have the red spots around the gills......if so could have been some dieseas (sp?)

I don't think the flow would have killed them....I have 2 clown fish in my fuge which has almost no flow at all.....I have a small mixing pump rated at like 40 GPH feeding my fuge and my clowns are doing just fine!!!!

Their were no red spots on the gills, they were just red in general. So far I'm up to 10 dead. But I did find a chromes that survived (1 out of 8). My Yellow Tang and my Blue Tang are both deceased :sad: . I'm still hoping to fing my sixline wrasse, he's been in their since I started the tank a couple of years ago. Do you think the anemone could have anything to do with it, he's still alive.

Does your tank have a deep sand bed? If so how did you move it?

Maybe oxygen was low?

Sounds like that to me, too.

Lack of surface agitation, perhaps?
What size is the tank?
Overcrowded to begin with, maybe?
How was/is the breathing of the remaining fish? Normal? Rapid?

HTH.

Cheers,

I'd put money on it.

Could be low oxygen, but if the powerhead was still pushing water around, maybe not. You say water quality is good. Just to be on the safe side, what are ammonia and nitrite readings?

I was thinking this myself. What if the tank re-cycled during the move???
