It's only forever; not long at all...
So? Plecos grow. I'd imagine they're common plecs which get to about 12 inches, or sailfins which get to about 20. Please do not tell me they grow to the size of the tank, that is stunting and while the outside of the fish may not grow, the insides carry on and the fish dies a slow and painful death. Get guppies then, but prepare for them to die. An awful lot of people can't get guppies to live very long even in a matured tank. Speaking of mature, it seems you are not. Have fun with all the dead fish ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
