Just needs some fish and it will look great.
very cool, looks great-thanks for sharing.
Wow, seventy five? that will really look great, make sure you post some photos please.
What kind of turtle do you have? I'd be careful keeping them with cardinals.
Looks like a red ear slider??
You know, I looked at the pictures about a half dozen times and never saw the turtle!
I would be careful with keeping small tetras with the RES. I have an old female, probably about 8" shell, and I am pretty sure that she would swallow a cardinal in a heartbeat if she could catch it.
If it can catch a cardinal tetra then it's just a gourmet snack.
I wish I had more space to take them on for you, but i don't think my current tank is big enough. Hopefully you can find them a good home.
