My 50 gallon corner tank has been setup for about 7 months. Everyone is healthy and happy but I'm looking for some help with stocking and lighting. Here are the specs. 50 gallon corner tank Magnum 350 canister filter with Fluval media Air bubbler with 6" bubble bar on a timer with the light Single 24" fluorescent bulb fixture Small gravel with substrate mixed in and fertilizer pellets Live plants Light and bubbler are on a timer from 7:30am to 10:30am then off until 1:30pm and on until 7:30pm For fish I have 2 South American Firemouth Cichlids 4 Tiger Barbs 7 Gold Barbs 1 African Leaf Fish 1 Dinosaur Bichir 1 Plecostumus 3 Upside down catfish 2 blue gouramis 1 Chinese Algae eater 4 assassin Snails I am wondering what interesting fish I can add to this group. I know the plecostumus is going to outgrow the tank eventually. Everyone seems to get along pretty well. I thought about a crayfish but I think that will do a number on my plants and may go after some of the fish when they sleep. The Firemouths like to sleep in my Sword plants and would be an easy target. Shrimp would probably be eaten along with freshwater crabs. I think my lighting is a little weak given the depth of the tank. Some plants do well and others don't last. I have room for another 24" fixture or maybe go for a more powerful or better spectrum light. I know LED is popular but T5 might also be a good option. I'll get some pics when I get home Sunday. Thank you all for your advise!
