New to this site. Its huge!!!! Anyway, I have been playing around with freshwater fish for bout 7 years now. Still have much to learn. Now I have a 900 gallon tank. I love it. Currently it houses 1 flowerhorn, 2 managuense, 2 firemouths, 2 yellow labs, 3 various peacocks, 2 red devils, 1 yellow agra, 4 plecos, 1 silver catfish, 1 longistones???, 1 leaf fish, 4 redbelly pacu, and 1 giant gourami who is sick at the moment and convalescing in a isolation tank
