I am asking because I might get some guppy’s or mollies for hair algae control in the refugium…These will be from the box store so all disease free bets are off

Not usually because of osmotic pressure. Not sure on bacterium though.I am asking because I might get some guppy’s or mollies for hair algae control in the refugium…These will be from the box store so all disease free bets are off
As in treating freshwater ich with salt and treating saltwater ich with fresh…. makes senseNot usually because of osmotic pressure. Not sure on bacterium though.

I still dont think fresh water ick or velvet can take being in full salt so even if it did get transferred it wouldnt survive. Again I dont know if there are any bacteria pathogens that can transfer between the two.Where it can happen is w

There is some crossover from Mollies according to some posts in this site - and they can act as reservoirs for Ich. I would tend to use mollies as compared to guppies for what you're planning. I would quarantine them using a freshwater protocol, then transition to saltwater over 3-5 days - then add to the tank. @Jay Hemdal has more information on this!!

I would also include @Jay Hemdal and the rest of the team. (note we are not the reef squad - but rather 'the fish medic' squad. Thanks for the complimentEvery time any of you Reefsquad folks take the time to bother I sincerely appreciate the work … not kissing bottoms but my face is close (or does that sound worse) lol

Yeah guppies sometimes pick at algae but that’s all mollies do …I would tend to use mollies as compared to guppies for what you're planning.
Indeed, that was a glaring omission, especially since I might annoy him, RHF and a few other mods…Much appreciate the FREE customer service from fellow hobbyists,,, Your jobs erh volunteer assistance is very appreciatedI would also include @Jay Hemdal and the rest of the team.

Yeah me too. I am pretty sure on the ick and like but bacteria and viruses I am unsure. Lets see what the big wigs have to say.What about something lymphocystis disease? According to google it can effect both saltwater and freshwater fish, but I’m not an expert.
Following this thread tho as I recently started working part time at a pond install company taking care of their koi’s and don’t wanna transfer anything to my reef.
Interesting that you mention this because we keep almost all the Koi pools between 4-6ppt to help deal with things like flukes if they are showing issues and we find something with a skin scrape/scope.Most of the issues I've heard of where freshwater fish carried disease over to marine aquariums were related to the "freshwater" fish being housed under brackish conditions (or at least some salt). 4 ppt is enough salt for Amyloodinium (velvet) to survive, as well as some flukes.
@GlassMunky mentioned Lymphocystis - that could be possible, but only a few freshwater species get that (glassfish for example, a marine derived species).
Internal parasites of course easily go between freshwater and marine fish (since internally, they have the same osmotic balance) but in most cases, they are transmitted through predation.
Bacteria are a wild card - many species survive transferring from freshwater to marine (we backwash our filters with city water and the bacteria lives just fine). However, most bacteria are ubiquitous, and are found in all systems eventually.

I do tend to wash my hands after being in or handling any of the Koi and I Shower immediately when getting home as well.
Thanks for clarifying!The koi would have to be exposed to brackish water flukes, otherwise, the purely FW species won't transfer over to marine tanks, ever. I should have been clearer: fish housed in brackish water can develop brackish water flukes if exposed to them, and those can transfer over to marine fish. You'd have to mix something like lookdowns with your koi for that to happen (grin). This is more of an issue for fish farms and pet stores that mix a lot of fish from a lot of different regions.
@Jay Hemdal - so - just out of curiosity - if one kept koi in a somewhat brackish environment - can they also 'catch' velvet?Thanks for clarifying!
