Well I noticed that Petco is having their dollar per gallon sale and I've been wanting to get a 10 gal for a while but haven't seen any good deals. Anyways I was looking at what I could stock it with and I came across multies. I was thinking of getting maybe 5 or 6 in a 10 gal with an Aqua-Tech 20-40 as filtration. Would this be too many for a 10 gal or should I get less? Thanks in advance
