There's seven discus in this tank I was only going to get six but the website I bought the discus from shipped it twice, they were extremely nice about it and only told me to write a good review which I later did. I have two purple leopard discus, two yellow marblo discus, two red marblo discus, and one blue checkerboard discus which I got from http://m.liveaquaria.com/ the other six discus including the new breed of purple leopard discus is from http://somethingphishy.com both very good websites super pleased with the results I got from them as youth discus. Somethingphishy was way cheaper I got three discus for the price of one at aliveaquaria well technically six but they doubled shipped my order because of something confusing about shipping the African dwarf grass plants. But both websites are absolutely amazing the way they shipped my discus, couldn't have been happier. If you're wondering what other fish and plants I put in this tank here's a list: 2 Bolivian Rams(both male) 2 Electric Blue Rams(both male) 7 neon tetras 1 fin spotted Pleco 1 Cory catfish 1 African dwarf frog DISCUS: 2 marblo red discus 2 marblo yellow discus 2 purple leopard discus(my person favorite) 1 blue checkerboard discus Plants: 2 Bamboo(straight) 2 Bamboo(twist) 1 moss ball 8 African dwarf plants 1 vine wrapped plant And some other plants that came naturally and I have no clue how they got there:) Specs: Tank size: 40 gal breeder Gravel: fine crystal clear sand(you can get this from eBay it's safe for freshwater and saltwater my dad uses the same gravel for his coral reef tank but it does raise your PH so be careful) PH: 7.0 Water temperature: 83 degrees Fahrenheit LED: finnex planted 24:7 Filters: canister filter(white) 240 gal(with uav light to kill viruses)& a 10 gal filter (used for water movement) Heater: theo, hydra(-brand) Bubble wall: something from petsmart I don't know what exactly it's called sorry:(
