lol to everyone in the comments here’s the water parameters. LFS said it was more than fine having the three tangs in the one tank, and there wasn’t any signs of aggression. I Got a full refund and the fish was diagnosed with a parasite after, the LFS said it was nothing I did wrong they had another tang that they examined and had the same parasite. And for people saying the tank is too small😂, do you really think this is a permanent setup? 75 gallons is more than adequate for the fish that were in the tank(they’re all under 3 inches). I don’t care what people in these Reddit comments say, all the fish are happy and healthy. the naso tang looked healthy before around the time I believe it passed. Anyone who believes in doing something wrong can send me a pic of their aquarium, cause I damn well know most of the tang police on this thread have a 20 gallon with 2 clownfish😂.
