Tiger Barb Help!

[mrjingles]

Hey,
I just wondered if anyone could help me, i have got 4 tiger barbs (2 green), 2 mollys and a catfish. Recently one of my tigerbarbs died and i wasn't sure why exactly. He started flipping around the tank, acting dead and then was ok for a while but he wasn't with the rest of my tiger barbs The next morning i found him dead.
A couple of weeks later and now 2 of my tiger barbs are constantly upside down. They are eating but are acting strange. Does anyone know what the problem might be?
Thanks alot.

Need to look at your water stats first in ammonia,nitrite,nitrate,and ph.
Are the fish bloated.
What do you feed the fish.
Any signs of flicking and rubbing against objects.

The fish don't seem to be bloated, i feed them tropical fish food everyday and bloodworm every now and again. I also feed my catfish pellets. They do flick off of the plants in the tank though.
Any ideas what the problen is?
Thank alot again.

Without water stats its hard to say whats going off.
Take a sample of your water to the lfs and tell them to write the readings down for you.
Improve there diet with a variety of frozen foods, and veg.
