I don't know where to start. i can't seem to find any visible symptoms. i've had about 5 young leleupi die over the past few months. every time it's the same signs. they stop eating, their stomachs become sunken in. they slowly lose their equilibrium, and then they eventually get picked apart by the other fish and die. well, until now it hasn't really bothered me. now, my adult male leleupi is showing the same signs. the confusing part, is that he's in a different aquarium. i looked at him for quite a while, and i couldn't find anything visibly wrong with him. i checked the water out, amonia and nitrites were 0, and the ph was 8. i didn't check the hardness, because i am lazy. does anyone have a clue? they start off not eating, and then they start to fade in color. i'll post a photo of my male leleupi soon maybe it can help. thanks in advance.
