Last october I lost a female betta while I was visiting family, May, and tonight I fear I'll lose a small female I got earlier, Hope.
(I only got her this afternoon. She and her sisters were being kept in a sparsely decorated tank with a bunch of gourami's and they all still have stress stripes. They aren't even an inch long, I don't think. They're being kept in gallon tanks at the moment, but...) Years ago, before I knew about bettas, I also lost Perceus, Rubiks and Riddle. Perceus survived about a year, but the others only lived a day... It makes me feel terrible, but I feel happy at least that they don't suffer any longer.
RIP May, Perceus, Riddle and Rubiks.
