So, Cryo currently lives in a filtered 2.5. He's got a case of SBD that I can't seem to shake, so he doesn't really use the space he has, and it's a challenge to get him fed because he has to come to the surface and sit on one of the structures to get at the food.
I put him in a little critter-keeper type thing the other day, maybe a half-gallon, while I was cleaning his tank. I threw in a plant to give him some cover and so he could sit near the surface.
He liked it. He was still just as lethargic, but the lower surface means he can get air easier, and he just seems less frantic and strained overall.
So.. should I let him have this one? Let Cryo live in a little, unfiltered critter keeper?
*Sigh* I don't know what to do with him anymore. Like I said, his SBD doesn't seem to be getting any better, and after a certain point his fins just stopped healing, regardless of what I do to help them along....
