I am trying to decide on what the last batch(es) of fish i can put in my aquarium. I have a 30 gallon hex tank, a penquin bio-wheel 125, an aquarium air tech gang valve that powers 4 airstones-(two 6- inch and two 1- inch airstones) All Nitrates, Nitrites and ammonia are undetectable, Ph is neutral, about 7.2-7.4, alkalinity is moderate, and hardness is soft. I have 5 albino cories, about 1 1/2 inches in length, 4 ghost shrimp, and 5 zebra danios, also 1 1/2 inches in length. I was wanting to add guppies, hatchetfish, and/or glassfish, but i am not sure how much or how many of each i should add if i can add them. Someone Please Help!
