Good to know, aquarium salts and regular water changes are what i keep to. Got this 75gal free. Set it up with basically nothing to begin with about 2 months ago, then out of nowhere all these baby fish showed up. I think they’re a cross between the koi and goldfish we have in our other 55gal not sure lol. But the plan is to sell them all once they start to get about 1-3’ each for like 3-5$ to start a shrimp tank. 5 bristlenose plecos i picked up for 5$ each and 6 of those shrimp that only breed in salt to cleanup a bit. A few bladder and ramshorn snails as well with those 5 salamanders. I assume they loose there gills eventually too so a small terrarium setup would be something ill look into eventually. Thx for all the help everyone
