Here is my 300 gallon tanks that I have had for about four years. It is 7ft long, 30 in wide, and 2ft tall.
First off, my Dovii, a wolf cichlid from Nicaragua. He is about four years old.
Then my Clown Loaches who are about six years old, there are four and use the rocks as hiding space from the Dovii who is always looking for a snack.
The Royal Plecostomus, about four years old.
And finally the Texas Cichlid. He was not fond of showing himself to the camera but, we (my father and I) caught it at one of the local lakes.
Sorry about the horrible picture quality, I am not what you call camera savvy.
