lol
a 30 inch dat, has anyone seen the pic of that? someone here has a gallery pic of one...
its not really a question of how good the conditions are so much so as the size of aquria and evental length of time we raise them for.
I doubt anyone has managed raising the mekong giant cat or arapaima to full size in a pond either, its just too large a size that a confined space would offer any fish the amount of swimspace to stretch out and becom full size.
Besides, dat's live in the mekong and its tributaries etc... water isn't perfect there... yet they get to 30 inches?
