Yup, i just received 2 res, about 3-4 weeks ago. I've been pulling my hair out trying to get these guys comfortable (male and female). Their about the size of a large hand, and poop like cats.
When i got them they were in a short 20 gal. tank with very little room to roam. They are in a tall 20 gal. tank right now which seems to be lots better for swimming room. On the rare nice days we get around here lately i let them go in the kids pool for the day.
Tank has a Fluval 2 and an old power filter, waterfall type, large turtle dock, and a clamp lamp with a plant grow lite. I have been doing complete water changes at least twice a week and rinsing the filters out, and use bio-terra water conditioner/cleaner? stuff. The clear water lasts for about 4 hours then it's cloudy. Just lately i started using a gravel vac to clean the leftover food and stuff after supper. This seems to help a bit.
In the next week or so i'm planning on a larger tank, 60-100 gal. maybe. Any tips on the filter types? I would like to use something that could be used in an outside pond in the summer then brought inside for aquarium use in the winter. (but not necessary, pond can wait) I've been having thoughts in using a pool pump and filter.
