he's sharing a tank with an equally ferocious Betta fish,named Ramone.I got Gamera's name from the giant turtle that fought Godzilla...you know,the one that had rocket boosters for flying. figured it was the only name that would do him justice.
so far,so good. honestly,the betta is physically the same size as the turtle currently,so I was more worried about the turtle catching the Beatdown.But there's plenty of plastic aquarium plants for climbing/hiding/basking,so they can hide from each other if they need space. Muds and Musks aren't really the best swimmers anyway,they tend to do more bottom strolling than anything else : the plants make it easier for him to get to the surface for air.
