Hi there...I have a 10 gallon tank which currently is the home of 6 red eye tetras and 2 panda corys.We would like to add 2 red wag platy's and 2 more panda's.Would this be overstocking? My concern right now is that I do not have enough cory's for them to be happy....I read somewhere that there should be 4 or more together, but in the future we would like to get the platy's to add some color in the tank. I know the 1 inch per gallon rule is not concrete, that it depends on the fish, but I am too new at this to figure out if this proposal would work - thanks for any help!
