Can Oscar live with Tiger Barb?
Not recommended
Why
- Oscar’s mouth is big enough to swallow Tiger Barb (only 2.75" long) — it will be eaten.
- Oscar is aggressive and will fight with Tiger Barb — two scrappy species in one tank means constant territorial conflict.
- Tiger Barb is a fin-nipper and will shred the long/flowing fins of Oscar.
