I have a 90 gallon tank with 4 different live plants in it, some larger boulds and caves and a gravel bottom. Right now the tank has 2 (3") Bala Sharks, 1(3") Rainbow Shark, 3 Tiger Barbs, 1 (2") Clown Loach, 7 Neon Tetras, and 1 (3") Plecos alge eater. The neon tetraas were the last addition to the tank a month ago or so. They provide some nice color and activity also. I just think I would like maybe 2 more fish varites in the tank. Give me some ideas as to what you guys/girls think would be good ideas. I'm not opposed to getting more then that, but just not sure how much the tank can really handle. I do 10% water changes almost every week at the most every 2 weeks and have had no water quality problems with the tank since start up 4 months ago now.
