He's eating!!
I dumped in some thawed brine shrimp in an attempt to get him to start eating (the only one thats left) and he kind of hid in the corner for a while then slowly started trying some of the shrimps, like he wasn't too sure what he wa supposed to do with them. After getting a few down he got a little more enthhusiastic about it.
Now, what to do with this guy? I have my 30 gal amazon tank, he could go in there for a while but its a flourite substrate. the other option is to keep him in the 15 barebottom for a while. Either way, I'd like to get a 55 set up and get like 3 or 4 more. Which would be the best option for now? I really appreciate everyond who helped me out with this whole process, I'm glad I was at least able to save one.
