My tank right now has 10 fish (4 BAs, 4 neons, 1 Siamese Algae eater, and the new small eartheater!) I wanted to eventually add some small tetras (saw some at a store yesterday, very colourful and small). How many more fish could I have? Or snails? Or shrimp? Or anything else you could recommend? Thanks!! Btw...My siamese algae eater is being really agressive. I threw a sinking veg tablet in there for him, and a BA tried to take a bite and he snapped a few times. I understand that..but he is still going around biting/hitting anyone that he passes. Thanks!
