Oh, for sure :)
And for lunch today I stopped into Petsmart to look for a larger home for him. I found this:
I know it's actually meant for reptiles, but I like the shape and the fact that it's rimless :) The employee said it can hold water, so I bought one for Cosmo. I'll be going in next payday to get a heater that will work in a tank this size. :D I'll eventually find an LED clip-light for this, but I'm not going to rush that since the room he's in gets plenty of natural sunlight.
It's 5 gallons :)
