I should probably explain a lil better about the situation. About six months ago I found a baby hatchling on my doorstep. I took him in and bought a ten gallon tank for him (the one pictured on bottom). Having him got me motivated to do something that I always wanted to do which was to build a HUGE aquarium. I learned to love turtles but did not want to plan a tank strictly for them cause I don't know if I really wanted just a turtle tank(I love watching cool fish too). So my plan was to build this huge acrylic tank and keep him as long as possible until he's bigger and can scratch the tank. About 2 weeks ago my cousin called and while doing her landscaping she found six baby hatchlings. We were going to be having some storms with some really heavy rains that night so she wanted me to bring them in. I had just finished welding and painting the frame for my tank so I told her I could use the small tank for them and went and picked them up from her. My plan is to use the tank to raise the hatchlings up to a decent size (about 1 1/2" to 2" and let them go in the lake outside my house. My cousin wants to take the bigger one and put him in his 55 gallon when I'm ready to give him up. Once all of the turtles are gone I'm going to have the tank ready for anything I find interesting and want to put in there. That's when I'll need your guy's good fish advise. That is if I can't find a way to keep the turtles. Anyways that's the story on the tank for now and ill keep posting updates and pics.
