Okay, so I'm really new to this but I will do my best to be clear and hopefully someone can help me out!
I have a full cycled 10 gallon tank. I ordered 3 otto cats and 3 dwarf puffers from my
LFS and the ottos came in first. So I brought them home and got them acclimated. Three days went by and they were active, appeared to be eating algae off of everything and they appeared healthy - round, white bellies and good color. I tested my water EVERY day and got perfect readings (0
ammonia, 0 nitrites, and low nitrates). Fourth day, out of nowhere - one is dead. Fifth day, everyone is fine but I'm worried maybe they don't have enough to eat so I give some zucchini - which they munch on but not a lot (so I took that to mean they weren't all that hungry - therefore getting enough from the tank). Sixth day, I checked on them when I started testing the water - they were both fine and good color. I came back five minutes later to check the test and one was laying in the corner not really moving but not quite dead. Five minutes later when I checked again - he too was dead. The next day, in the morning the final otto appeared fine. By evening, he was floating - dead. So I cannot figured out what went wrong. Maybe someone can help? The fish had round white bellies (didn't appear starved) and I read if they had parasites their belly would be red - they weren't. The LFS had ordered five so he still had two in the store when I called after mine died - his were (and are) still alive. So I don't know what on earth I did wrong? If something stressed them out too much or what?
Does anyone have any ideas what might have happened to my ottos? I don't want to bring my puffers home and kill them to if it's something I'm doing wrong. I read about the cyanide with the ottos but that doesn't make sense cause the three I took died but the LFS's are still alive. I just don't get what I did wrong. The LFS had me bring home one of my puffers to see how he'd do and I'm so afraid he's going to die that I'm constantly checking on him, lol. I just don't know what to do - especially if he dies too! ANy advice or thoughts would be most appreciated! Thanks in advance.
