Can 2 oscars, bala shark, pleco, and 2 silverdollar be with clown loach and angelfish?
- The oscars are still babies.

Just take care the bala doesn't fit into the mouth of your o's, and keepin mind that mouth will grow just as fast as the oscar itself.
I had a chinese algae eater in with my baby o, and all went smooth.
Until i found this sight one morning after 3 months...



I've seen the combo with angelfish work, but i also know stories of failure...
Again, angelfish are famous fin nippers and an oscar may not respond to that in a friendly way.

I think you should be ok, as long as you keep size and growth rate in mind... And I have NEVER had an issue with Angels nipping fins! I am sure it is possible, but I have never had an issue!
