Sorry to burst your bubble mate but they can't walk on land contrary to belief! If they are out of land for too long they will dry up...and can get easily lost on land thus making the chance that they will be able to go 300yards highly unlikely. True they can breath air for 3 days out of water, but they must remain moist or they will die. So many negative things said about them, where is the positive? These fish are TIGHT!! I just got some baby C. gachua...thankz to CFC's advice...and they are great fish. They are a dwarf species, much like orientalis, except different colors. I even think orientalis gets a bit larger, two inches maybe. And as for the aggression thing, thats true with most cichlids and large fish so don't think snakeheads are just out there waiting to attack...most don't. Gotta give them credit and know when to believe myths/tales and when to believe the truth. I love them and think they deserve much much much more credit than they get. And that whole thing in maryland and chesepeak pisses me off, just goes to show that some people shouldn't keep fish if they can't be responsible and plan ahead for keeping them!
