Fish Can't Swim Down

[Beanlekin]

I have some cherry barbs in my tank and after eating, they can't swim to the bottom of the tank. This usually lasts for about 30 mins and then they're back to normal. My other fish never have this problem. What could be causing it?

Most likely they are swallowing air when they eat. It just takes a bit for the air to pass. You can reduce this by sinking the food for them. Add your food to a cup of tank water swirl it a bit then dump it in the tank.
