OK so I had a issue with white spot and thats all cleard up has been for two days. Last night I went to feed my fishAnd noticed The clown loach was
just sitting in the corner of the tank not looking well at all. When i feed them he didnt eat or even move. he was drifting on his side then he would fight for a bit
then just tire out and float on his side. Sadly he passed away.This morning i went to check the fish and i have only 3 of 5 tetra left why could this be?

I assume the temperature is at 30 because you were treating for ich? If not then it's far too high for a community tank.

Angels eat tetras (even if they've been peacefully cohabiting until now).

The clown loach could have succumbed to the combination of high heat and meds.

How big are these fish and how long have they been together?

Are you using a liquid test kit?

 

[Miss.Ward]

Yes im using a master liquid test kit. Yes still treating for ich.. The have been together for maybe 2 months
