Newbie looking for some advice. I set up my 12 gallon saltwater FOWLR
in June of last year. For the first 4-6 months things went great. My water was clear, my fish seemed happy and healthy, overall no problems. Then one by one my fish started dying. I should restate that...they started disappearing, never to be heard from again.
I always started with the beginner fish and was as patient as I could be. I did not add more than two at a time, never bought more than two per month and I drip acclomated them over about an hour period. I have lost damsels, a sea star, and 2 a pajama cardinals over that period of time. EVERY time I check the stats on the aquarium they look great.
At this point I really am gun-shy about putting anything in there. The only living things in there currently (for about the last month) are a few snails (2 astrea, 2 nassarius), I would guess bacteria and otherwise not much else. My live rock is covered with coraline which I have fun scraping off the walls of the tank.
Not sure where to go from here. I guess it's possible that there is something in the tank killing the fish, but if there is it's in the middle of the night but I don't see much in the line of movement except for some long white antennae that wave around out of my live rock (I think they are spaghetti worms).
I should also add that the last fish I added were two domino damsels. They were gone within one day.
Here's my stats: from about half an hour ago:
Ammonia < .25
Nitrate ~ 10
Anyone have any ideas at all?
