I just bought 2 Dalmation mollies and 1 black one and also 2 tiger barbs and also 1 Red wag tail. The red one hasnt come out of hiding in hours and didn't even come up for food. I'm scared. What do i do??
I will go further, and strongly suggest you take the Tiger Barbs back quickly. These fish once settled will terrorize mollies. Tiger Barb need a larger group than most shoaling fish as well, at least 10, in their own 30 gallon tank is minimum. They are feisty fin nippers, and slow sedate fish will be hounded to death.
Mollies are not small fish, and need space too. Not knowing your tank size,I will leave this. It is the TB that are the "emergency."
