Hoping for your diagnostic help. I'm trying to understand what I have on my hands. Bacterial, Fungal, Viral, Environmental (e.g. toxin)? I don't think it's water quality.
In the last week, I've had the following fish deaths:
1) Glass catfish, ich and death
2) Betta albimarginata...
We have a male wild-type livebearer, who has taken kindly to a female wild-type betta. They are mating constantly and she seems to be a willing participant.
Do you think I should bring the limia back to the store? Is there any harm done by this sort of cross-species affection?
