So i bought a 5" elephant nose and the tank had ick i knew it did when i bought it but, I put the fish in its own tank and added the meds and later that night he was starting to turn white and it looked like his skin was stsrting to fall off and when i woke up he was of course dead and me snail had eaten off his fin and started in on his sideso can some one tell me why he died? i took him back to the pet store and they had a bunch of fish dead in the tank they blamed it on the power going out for like 4 hours! i think they were lieing what do you think?
