I have a 29gal comunity tank that has been set up for about 3 years. None of the fish are growing! I have had 2 golden gouromis and a pleco for the whole time, the gouromis have grown a little but aren't full size, but the pleco hasn't grown at all, he's about 2" long. But I have tons of algea for him to eat but he dosn't grow. I have had other fish in the tank that didn't grow:tetras, silver dolars, rosy barbs. Whats the problem, and is it bad for the fish to be stunted, I don't realy mind because they don't take up to much space.
Anyone know whats going on?


? Or is this all going to fall apart if I don't do a water change soon?
