It's been a long time since I had my senegal, but because my axolotl has similar spacing needs as a polypterus I thought I'd ask here. Has anyone used a really shallow tank(like a coral frag tank) to keep their polypterus? I'm talking like 8" tall tanks that are really wide. Theres a petstore nearby selling their old coral growing tank but its 36x36x8. I'd need to put a lid on the tank, but it would really put my mind at ease to hear about someone keeping their fish in a shallow tank with no problems. Otherwise the dimensions are amazing, and I would love to get a tank with that much walking space for my axolotl.
