Hi, I have a 29 gal
tank with an 8 inch plecostumus, three 2.5 inch rosy barbs, a 6 inch rainbow shark, and three electric yellow cichlids that I bought yesterday. I am doing research into what I could put into a 75 gallon tank that I am looking to buy. I want to have an african brown knife, two rainbow sharks, and four blue gouramis with the possibility of having a bala shark in there as well. Any opinions on how this tank would work out on paper. Thanks.
