Yeah those are the guys I looked at before deciding to use the polypterus as a culler. They are supposed to be water finicky, need live food and be kinda aggressive. I was looking for "gulp" monsters and night hunters.
they should not be sold as common pets no more than those vampire tetras, clown knives and oscars. You'll see a whole bunch of "oh no -heelp!" posts in 3-4 weeks..jus watch!
They are claimed to be messy eaters part of the time too >shudder< which is why they and the pike gourami were crossed off my list and obviously pirahhna (though I actually know how to care for those)....
Baby betta extras disappear over night is one thing.....baby bettas being made into sausage as you watch is another.... 8O
I've noticed many strange fish at "pet stores" lately. many are things better left alone or neeeding a city aquarium for care. Shovel nose cats are allover at my Petsmart. And so are some rare barely able to research stuff. I see bad trend
