One of the "freebies" I just got is an Eclipse 6 tank. I love tiger barbs (the green & orange ones) and they don't get very big, so I was wondering about putting 2 in this little tank? I know I can't put them in a community tank. What kind of bottom feeder or algae eater would do all right with them? My other thought is bumblebee gobys for this tank. I could do 3 or 4 in a tank this size, but I've read that they are sensitive to water conditions and may be difficult to keep? Any thoughts/feedback?
