So far there is no way to get the tanks to hold more than 20 fish at one time, that I am aware of. The only way to get "more tanks" is to purchase the one from the "supplies" store, then you will have 3 tanks.

Please tell me what you mean by "Yes i am a newbie..don't be a hater =p. I am a fairly new user of this forum also. I've been playing the fishie game for about 4 months.

I am really curious to know what your intro means.
