Something got into my sorority (& males' tank by cross-contamination) that is wiping out all of my bettas. The catfish are fine.
I'm going to wait and see if the rest die b/f taking the whole tank down. Beats me if I'll get a betta again. I love them b/c they aren't schooling fish; they are all off on their own little agendas- sneaking up on a catfish, looking at snails, exploring the tank, begging for food... it makes them so much more endearing than other fish.
4 bettas: Butch, 3-year-old violet male PK EE & 3 girls in a 30 gal sorority. I do not name the girls anymore! 1/2 of them die within a month.
30 gal: 9 Oto cats, 4 Ocellifer cats. Inverts: Cherry shrimp & 2 assasin snails.
10 gal.: Butch, his 5 oto cats, 3 assasin snails, and a few snails the assassins haven't caught.
