FW mollies with seahorses?
I know I read somewhere of someone keeping FW mollies with their seahorses. I wonder if any of you have done that in the past or are currently keeping mollies in their seahorse tank? When I serviced tanks for a LFS one of our customers had a FW guppy in their sump for years. ( I'm guessing it was a feeder guppy who went over the overflow ). Anyhow if some mollies were acclimated to the higher salinity they could make peaceful tank mates who wouldn't be bringing in ocean pathogens. Some of the sailfin mollies are beautiful fish.

I would like to see proper documentation on this topic as for 20 yrs I've been seeing that feeding fresh water fish to salt water fish can sometimes cause liver problems in the salt water fish due to different fatty acid profile.
As I don't know for sure, I make a point of never feeding fresh water fish to marine fish just in case. Keeping them as tankmates may be a different thing though, unless they reproduce allowing the seahorses to feed on the mollie fry.

I have never heard of a FW guppy being put into salt water as they are not naturally a brackish water species. On the other hand, mollies will do rather well because they can be a brackish species by nature.
I used to keep mollies in my fish only when I had a much larger tank. I used their fry as a natural food source for my banded shark. I never really had many babies make it to adulthood as the shark kept the population under control. Never noticed any health issues with my banded shark and had him for a few years before giving him away to someone with a larger tank when he outgrew mine.. As far as acclimation.. They are pretty durable. I acclimated mine at the time in a bucket w heater over the course of 24 hours, which is probably not ideal but it worked |

I had not thought about the seahorse eating the fry but that could be remedied by only getting females. |

I fed fresh water ghosts to a seahorse for over 8 years. He lived. I tried mollies s they are live bearing but after a few months I just had a ton of mollies. The seahorses never ate them .

I tried one in my frag tank for that purpose. It did nothing in terms of algae control.

I know those silver tip catfish they sell in the fresh section can be converted to full salt rather easy too.

Acclimate a molly slowly and it can live in a saltwater tank.
Silver tip catfish are actually heavy brackish/saltwater fish, I believe. I don't think you would have any issues with keeping them with seahorses. They're peaceful, not especially hyper, and won't compete with food too much. Now, I could see one nipping at the bumps on a seahorse because it thinks they're food... However, I think most seahorses would peck at the molly after they got annoyed. That or the molly would figure out that this thing wasn't edible.

I've also tried mollies for hair algae and bryopsis. No positive results to report on either. Peroxide, however, get's the job done!
I agree though, they were model citizens with a very timid group of fish at that point. I don't see that it would be problematic to house them with a seahorse. |

You can also easily convert most FW gobies, puffers, scats, monos, archer fish and some sharks. |
