I was in discussion today with a friend who keeps tropical fish. It came to the subject of Marine fish and Brackish fish. Although I do understand some Brackish fish can live with Tropical Fish, but I I am absolutely certain that NO MARINE fish can live with tropical fish or Brackish fish? Or could they? Can anyone clear this up for me please and would be so grateful for a list of brackish fish or Marine fish which may live with tropical fish. THEN I CAN SHOW MY FRIEND! many thanks you are all very wonderful x

Some fish can live in - eels and sharks, plus some puffers for instance. Some fish (salmon for instance) live most of their life in the ocean, but return to freshwater to spawn. Others do the opposite, living in freshwater ans spawning in the ocean.

The ones that are considered freshwater tropicals that can live in saltwater are probably more correctly classified as brackish, but these include mollies and guppies. I've acclimated both to saltwater myself for cycling marine tanks. At one time, I only used mollies, but with the popularity of nanotanks, I've tried guppies recently. They take longer to acclimate, but seem to be even hardier than the mollies in full slat. I even have a trio that are breeding and raising fry in a saltwater tank.

no - one is freshwater and one is saltwater. Some freshwater fish eat feeder fish (guppies and rosie red goldfish) - if you put the feeders in a saltwater tank they would die. Tropical fish are freshwater fish. Marine fish are saltwater. The fish and their tank maintenance are completely different. Brackish fish are more of a combination of the two. A marine/saltwater tank is far more difficult to keep - you need skimmers...etc. A basic web search or a call to a decent fish supplier should be able to provide you more detailed information. I have three tanks - two Cichlid tanks and one community tank, no marine/saltwater tanks. Marine fish are beautiful in colors, more so than the freshwater fish but they are also more expensive and like I already said, more difficult to maintain. The salt in a marine tank would kill the tropical fish and the lack of salt in a freshwater tank would kill the marine fish. Would fish from a lake make it in the salty ocean? No, they would not.

I believe mollies are a brackish fish that can be SLOWLY acclimated to live in either fresh or saltwater.

Mollies are brackish water fish, and they can live in freshwater and be slowly acclimated to saltwater.

i've really never heard of tropical fish living with marine fish.Unless you are talking about brackish fish they live in both salt waters and freshwaters.but as for cichlids livng in a tank with clownfish(NEMO),i think Nemo would laugh(get it clown fish).because they would die.LOL
