I keep thinking that I should put a little tank on my desk at work, maybe a 7 gallon bow front. What fish would you keep in such a situation?
I was thinking that dwarf puffers would be great but at least some people who keep them say they are not the best candidates for fasting two days a week. And they tend to like live food which is a little hard to provide at work. (Can't you just see the face of the co-worker who comes across wriggling
blood worms while snooping in the frige

?)
Would a seven gallon be large enough for breeding a pair of blue rams? Or how about some Tanganyikan shell dwellers? That might be the coolest but I've never kept them.
Any ideas for me?
