Can I keep Goldfish,Angels and Sivaram with Discus? How about livebearers like swordtails, mollies, guppies or platys?
When you keep many fish of different variety of fish together in one tank, you should consider the following:
Will all the fish take the same food you give?
Will their living habit the same? Like water quality . . .
Fish of different sizes can they live happily?
If you have no choice but to put them together then do it and observe them.
Help your fish to settle their problems if any.
