take the angel fish back i have some they get big and need at least a 30 gallon for just them 2 alone. after that you should replace them with 2 female sword tails and 1 male swordtail. unless you dont want to breed them then get all males. and some platy's. thats about all you can put in a 10 gallon aquarium, for agae eater dont get the big black 1's the plecosomise one that i cant spell because they will get big. get a little cleaner fish there pink and suck on the tank all day long pretty much. and they wont get big so get one of those.
