Yes, the film canisters had a hole put in them roughly the size of the suction cup inner, then I removed the hook part and just jammed in on the film canister, think that it works out really well. Right now I only have 1 "male" almirante and 1 "male" basti in the tanks to establish their territory. I will introduce the females next week. I also wanted to separate them to see if I would induce calling. I plan to have a pair of each in their own tank. I received a pair of almirantes and a pair of bastimentos from Glenn. When I spoke with him when these frogs came in there were mostly almirantes and very few bastimentos, I ordered more bastis but only received the "pair". Of the two bastis the female was nice and plump, but the male was extremely skinny and had a shipping injury on his left wrist. I treated the male to stop bacterial and fungal infections and he is the one in the pic putting on some weight and being extremely active. I received the fantastics "pair" from frogwild/Anthony who was a pleasure to deal with and speak to as well. I put all sexing terms in quotes as none are proven to be a male or female yet......
