I had to rehome one of my Betta imbellis, so I'm down to just one now. The two males I had were brothers, and they got along beautifully for several months, but quite suddenly one turned against the other and began chasing him relentlessly. It makes me sad; I really liked having both of them in there, but it's for the best. These fish are certainly more peaceful (and much prettier, IMO) than splendens, but I think a 36" x 9" tank just isn't big enough for a group of them. When I had a male and female, the male hounded the female so badly that she died before I could find her a new home, and when I had three males, the two younger ones ganged up on their father.
Everybody else is doing great. Plants look fantastic. The paddy herb and water fern are not as lush as they once were, but the christmas moss is more than making up for it. I still have all five of my original
Pangio cuneovirgata, happy and healthy. They are really, really cool fish, adding a bit of mystery to the setup. Lots of happy amano shrimp scuttling about, and the trumpet and assassin snails are starting to achieve a nice balance.
The eight dwarf rasbora (
Boraras maculatus) are doing great, but they've never really colored up that much. I prefer the look of chili rasboras, but those don't fit my biotope. Maculatus are sort of a filler fish, I'd say: They give some movement to the tank, but they aren't very colorful and, other than their tiny size, they aren't really that interesting.
Next time I order fish, I'm planning to add a big school of emerald eye rasboras (
Brevibora dorsiocellata). I think they'll add a little extra color, and their behaviors sound really interesting. Thinking about trying blue rasboras (
Sundidanio goblinis), as they were one of the original reasons I started this tank. But they're wild caught, and they come from an endangered ecosystem, so it's hard for me to justify buying them unless I'm certain I can establish a breeding colony. And I am far from certain of that.
I made a new top out of pieces of glass, to reduce evaporation but allow the rice to grow through. The new water circulation system is working perfectly. So, overall, all is well!
