One of fish is sick. He is not eating and neither pooping.
It also looks like his intestine is hanging out of his anus.
Please please help.
I have a 36 G tank with 7 different species
I feed them 2 times a day
Temp is at 80F
I have a 5g office tank at work and had 3 1" guppies in it. One of them had what appeared to be a prolapsed anus. I took the tank home, added some salt, stopped feeding, increased the temp to 82* and he still ended up dying. From what I've read, nothing is a guarantee to fix the situation.
