I have my bettas in 1+ gallons. @ males in 20s (because they were empty.) and 2 in 10s, and females in 29. some in 1 gallons, because my desk has a computer, and I don't like divided tank xD I don't think tank size matters.... well, a little, as long as you have a 1+ gallon (breeders can use jars) and keep up with cleaning :3 cleaning is MORE important than a HUGE tank for one betta. (although if I won the lottery had a nice house one room would be the "large tanks with bettas" room) let's drop the "tank size controversy" in this thread that does not concern bettas nor tank size and love the crab :p
the last picture of the crab looks like "noooo no more pictures!!!" xD he's cute though. I like crab meat >.> but I couldn't cook live animals myself. or break their necks, or chop their heads off, or drown them.....or boil them alive.... I'm a "give it to me raw and dead or cooked, but not alive!" person =D often then not you find minnows, leaches, and shrimp here. I'm actually going to test out in an empty 20 (eventually) if minnows, shrimp and plants from a lake can survive tank live. but the tank has to be established and I have to have patience that day :) dare I find a goldfish >:(
Breed for the breed, not for the money; the words any REAL breeder would understand.
You must know nothing in order to know all, for all is nothing and nothing is for all.
