Comments: Dermogenys pusilla is the halfbeak most commonly available to aquarists. It is probably best to keep a few of them at a time, at least three or more. Wrestling halfbeaks are actually quite peaceful but they are not the best fish for a community tank. When kept with smaller fish or fish with long or flowing fins they can become somewhat of a nuisance. They might nip or harass the other fish a little bit. If you would like to do keep wrestling halfbeaks in a community it is recommended that you keep them with mildly agressive fish such as tiger barbs. Of course, all aquarists know that you should always be on the lookout for any signs of stress, nipping, bullying, or harassment.
These particular halfbeaks are not picky eaters at all. They stay near the surface so as long as the food doesn’t sink too fast then they will most likely eat it. Most foods will be accepted but you should try to vary the diet a bit.
