Just like the title says, my first fish in my tank. 16g biocube alk 9 sg 1.025 ph 8 ammonia 0 nitrite 0 nitrate around 5ish now phosphates 0. Why does he turn white at night? He swims around like a drunken sailor smashing into things. Ive had him for 3 days now no qt, and I cant figure it out. He eats copepods/ brine shrimp if I think its necessary ( usually has a fat tummy ). Hes a tad shy of an inch long. What is super odd is he is completely black again by day acting normal again. First time I seen him like this I thought he would be dead by the time I got off work. Any thoughts?
