Ok, first post. I took in a 10 gallon from my girlfriends parents when they moved which had a tiger barb and a common pleco. This was my first tank so I did a lot of reading and decided to adopt away the pleco the to pet store. I kept the tiger barb and now have a 29 gallon with 7 harlequin rasboras and 2 bolivian rams so far. The tiger barb has been alone in the 10 gallon for about 8 months now and seems happy but I read they are a social fish that need others. I was wondering if it would be possible to put a few more tiger barbs into the tank and not be too crowded. The tank has an aquaclear 20 on it and has a few java fern plants attached to some driftwood along with an anacharis. Thanks!
