Dead Mollies Everwhere

Prawns'll do that ans should never be kept with small fish

Unless your molly was ripped apart, I highly doubt it was the prawns.

Few questions we have to have answers to in order to help you:

How long has the tank been running?
What are your water parameters? pH, ammonia, nitrites, and nitrates.
How often do you do water changes and how much?

Thanks

That's a strange mix of fish, I hope your tank is huge.

Livebearers, sharks, tetras, barbs, CAE's, and gouramis. I think the lines of expected compatibility have been crossed.

I have 3 balloon mollies in my 30g tank and one day a female died then 2 days later another female died and then like a week later the male died. I was awtchin one of the females the day she died and she was prefectlyt healthy and then just died. I have 2 rainbow sharks (2-3in), 1 red tail, 6 neon, 2 prawn (dont no species), 1 tiger botia loach, 3 SAEs, 2 red gouramis, and 6 fully fully grown tiger barbuses. When I watch all the fish seem peaceful but I have my suspicions about the prawns because this started happening about a week after having gotten the prawns. Anyone know what might be causing this because all fish looked healthy and then they just died. When i find them they look pretty deteriorated and i think the CAEs and the prawns may be pickin their corpses for food.

I had a red clawed shrimp (prawn). The LFS said that they were peaceful and fine with fish. However, I came home to find him eating a very alive neon tetra. The tetra's back end was snipped down all the way to it's backbone. I made the shrimp let go and the tetra died a few seconds later when the rest of the fish in the tank attacked it. After researching it I found that they are "opportunistic" predators. I returned the shrimp to the LFS the next day and they told me that no one else had reported this type of behaviour and they had sold alot. I had also lost a bloodfin tetra, and one of my red gouramis had mysterious cuts on him that he had to be treated for during the 3 days I had the shrimp, but these two occured before the neon, so I am just assuming it was the shrimp. Here's a picture of the one I had.
Take care,

My Oscar would get along well with that guy. :
