how about getting 2 rams(pair) and two different schools, say 7 of each? Then you can get like 2 or 3 ottos = very helpful for staying on top of algae.
- i find cardinals more difficult than neons in my hard water, but I still like them more. You have to introduce them with lights off and even use the drip method for an hour or two then just plop them in.
- try searching for a cardinal v neon thread, i remember reading one that isn't more than 2 months old that had tons of posts.
-im going with cards and harlequins, 2 bolivians, and a few ottos for my 20usg tank.
