Hello. I am planning on setting up a river tank or something similiar. The tank is going to be standard 90 gallon tank(48"x18"x24"). It will be filtered by 2 penn plax cascade canisters, the 1200 and the 500, together suitable for a 180 gallon tank, both filters will have spray bars. The tank will be half way to 2 thirds filled with water, then the back wall will have spray bars(waterfalls) almost all along the back. The tank will have smooth river rocks for a substrate that will slop up out of water at one end of the tank, this will be the basking spot for a red ear slider turtle and will have a reptile light over it. Now there will be a deep end for the turtle(where the rocks are normal,not slopped),a shallow end(where the rocks start to slop) and a basking spot(where the rocks come completely out of water.) On the basking spot there will be a fake plant, so that the turtle can get some shade and also bask. All along the back of the tank will be sturdy, fake plants, wood and rocks for frogs or whatever to climb out of the water onto. On the side of the tank opposite of the basking spot, there will be a bubble wall. The lighting will be a normal flourescent light and a reptile light. The tank will be heated with a 300w eheim heater.The tank will have feeder goldfish and a red ear slider. Can I keep any sort of frog or something? And do you think this setup will work? Thanks
