did you happen to know they were going to bred or was it totally by accident. how long did you have them together as a pair?
Ed Hammer bought this from Aquatek in Austin. They paired it up for him. Then he had some babies in his tank. I bought it from him last December. He told me it was a proven mated pair. After I got it from him. I told him that if it indeed was a mated pair, it's going through a divorce. After all, the both of them were swimming around on the opposite corner of the tank. After a few weeks of them being apart. I saw finally one of them just starting to shake his body and fins continually in a ritual dancing manners. I think the male just kind of ignore it. Other then the male not eating, I didn't think much of it at all. I only found out tonight.

I've had several other Bangaii B4, they were wild caught and hard to feed. In fact, I ordered two Bangaii online last December. They both died off after about two weeks. The wild caught one were just picky about the food. They would bite, then spit most of the food out. That, or they were too slow to get food compare to my other fishes in the tank.
