I have a flame angel and just recently got a copper band butterfly they were both in quarantine tank and the last 2 days they were fine. Fed everyone yesterday and no issues. Woke up this morning and found my copper band dead in the bottom and my flame looks like his bottom half went through ww3. I asked to verify before I bought the copper band and was told they're wouldn't be an issue. I'm tired of feeling like all I'm doing is messing up.
