So, my brother is very into freshwater aquariums. And gave me a 55 gallon tank for my room about 3 months ago with a pair of blood parrots. A couple weeks later I got a bala shark. And a couple snails. (He has tanks for the bala once it gets to big). And about a week ago I bought four tiger barbs, three green, and three albino barbs. And the barbs are still very small. And so far they are all getting along fine. My parrots seem to be paired up but are still pretty young. But everything seems to be so far so good. Other than my barbs picking at my snails from time to time. I'm hoping everything stays peaceful in the tank. Would love to hear some people's opinions.
