I lost all 6 of my albino corys when I started introducing female bettas into the 29-gal cycled tank. I used the corys as fish-in cyclers, and they were normal, active fish. After about 6 girls, they went ballistic! They swam randomly, frantically, up and down rather than across the bottom as they usually do. Then, over the course of 3 days, each day, 2 died suddenly- like a heart attack!
I want more corys. I tore down that tank 100% after I lost a betta; then all the snails died. EVERYTHING got tossed (except fish) & I have built it back up. It sits here now; lit, cycled, heated, filtered with only plants and cherry shrimp. I'm terrified to stock it again. The remaining girls are in my 10-gal "hospital tank", and have been for 5 weeks.
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.
