Hi all,
They feed on molluscs in the wild, but anything they can swallow in the tank (fish, air stones, fingers etc.). They are fairly easy going in terms of water conditions, but they are big and very aggressive (I don't mean they are aggressive for a normal fish, I mean they are aggressive compared to a trimac, red devil etc.). Your best hope is the RTC eats it before it can do too much damage.
