yesterday my yellow wrasse failed to show up. I expected something is wrong so I tested the water and I had ammonia reading of 0.5
I swifted through the sand and found him.. he came out and hid behind a rock and stopped moving completely. He swam a tiny bit and wouldn't come out from hiding then disappeared again.... (Usually if I disturb him he will come out and rocket around the tank and dive straight down again..)
I changed 25% water and put one "Ammonia Clear" pill and the ammonia tests at 0 now. Nitrate/Nitrite are all ok.
Is there anything I can do ?
I've had him for 1.5 years now..
I have two other clowns in the tank and they're perfectly happy. That's everything that's in the tank.. it's a 30G, no corals, no inverts/snails any more.. all died within 2 years. I use RO
water and Instant Ocean salt. Fluval 304 filter, no skimmer.
Also recently my Actinic bulb burnt out and I didn't replace for about 5 days
Maybe that's what caused the ammonia spike right after I put in the new bulb?
I also haven't put anything in the tank for a long time.
Thanks a lot!
