Acquired: Fish / pet store
Posted Apr 11, 2013
When I was about 10 years old, I had a fish tank that had a good mix of common tropical community fish (tetras, swords, gouramis). In a 30 gallon tank, I had a school of 6 Gian Danios. The fish did well in a school and were very active. However they were very food driven and tended to be hogs about eating. You could never give them enough food and they tended to be so active that you couldn't really appreciate the other fish in the tank. I wouldn't say they were aggressive towards the other fish, but more of a distraction and detracted from the balance of having a mix of various breeds of fish. In my opinion, these are fish that are very easy to keep but you may wish to keep them in a tank that features them as the main breed. They never had sickness or caused injury to any other fish but just were not as appealing as other fish I have kept to the point that I ended up giving them away to a friend with a larger tank.
