I found that frog on a rock then I put it back the person I got the fish and tank from had goldfish with the discus and the discus like 84 F wather, gold fish like cold water. so I took the goldfish out recently and put them in a pond in my back yard and I didn't clean it enough. they gt stuck under rocks, they almost died. that want smart but I just got a tank from them http://i462.photobucket.com/albums/qq347/booglue33/IMG_0247_zpsnjwdkbx4.jpg

I have i think it was a 50 gallon tank? Its all salt water and i have one clown fish some other blue fish and a black one idk the names since someone else bought them. I had more fish but they died for some reason they all jumped out of the tank and one fish died because the blue fish was a bully and hit it on the side and it sank to the bottom of the tank. Also had a star fish and 3 hermit crabs in therebut the starfish ate the crabs which died and after the star fish died i had to take it out

one of the discus jumped out the water the other day and some parts of the tank the fish could easily jump out of the tank. hope that doesn't happen
