Betta brownorum

I keep these fish at 76-80°F. I use tap water (pH 7, 220 ppm) that has oak leaves and filter bags of peat moss added (I just put the bag in the tank). Malaysian driftwood also helps color the water. I usually keep floating plants with them also. It's not necessary to remove the parents after spawning, the father takes care of the babies until they leave the nest and neither parent bothers the young after they leave the nest.

Most spawnings I ignore and let the fry fend for themselves. You just find young fish in the tank later. With this particular spawn I saw some babies fall out of the film canister and then the mom darted over and ate them! The male chased her away but I decided to pull the film canister out. I took a picture of it below. Removing the fry probably leads to higher numbers of surviving fry, but it can be tricky. If you remove the eggs they won't hatch. I think the male needs to mouth them to get them to hatch. But if you wait too long the fry leave the nest. With this batch the spawning occurred on 10/14/05 and the fry were pulled just before they got too active, on 10/18/05. It's likely that some fry had already left or been eaten. I've seen spawns of 50 or 60, but this canister has about 20 fry.

Well, here's an update (1-3-06). I have raised the roughly 20 fry that were removed in this film canister but about 40 (or more) fish had already left the nest and are still swimming happily with their parents! I might as well have left them alone. I also just saw a book that showed pictures of wild caught brownorum and not all of them had spots. This makes me feel better because I was wondering why so many of the fish I've raised don't have the spot on each side. What's really strange is some fish have a spot on one side and not on the other!
