I love mine. Ours are in a 120 with syno cats, jack dempseys, clown loaches, fire mouths and giant danios.
They love to hang out in the plants and around the wood. Very easy to care for as long as you keep their water clean. Ours eat any and everything; cichlid foods, my home made fish food, shrimp pellets, frozen foods.
Don't try to catch them in a net, their pectoral fins are like daggers and they will get stuck. I've also actually had one that jumped out of the bowl I caught him in and land with his pectoral fin stuck in my foot. They are mildy, very mildy poisonous, so if you have allergies to insects, be careful. It took me a month and tons of benadryl to heal
