i have a white top african cichlid that is holding. i put her in a 20g tank that just had plants in it. well its been about 2 weeks and the fish is doing well and still holding. but the tank has grown alot since i first put her in. there is alot of algae growing and the plants are larger and the tank looks pretty dirty. is this ok for my young white tops? the water conditions and fine and temp is at 80. is this ok? will the young fry eat the algae?
