Hydra info link
In my 20 gallon tank I'm using for a quarantine tank, i discovered some green hydra living in there! I think they are kinda neat, but don't think they should stay, don't want a lot, or to get them in other tanks. I have a few fish in there finishing up their Q time, hope when moving them i don't spread the hydra. moving method trasfers no tank water, so i think i'll be ok. I guess i'll just break down the tank when the fish are moved and start it over, as the other methods seem impractical to me, copper, other chemicals, heat to 104 degrees, I dont think so. 3 spot Gouramis eat hydra, but I don't like Gouramis (personal choice, please don't kill me!)
Y'all think Im safe to move the fish?
Then bleach ad re-cycle the tank?
Any other suggestion would be welcome, that's all I found online, except chemicals only available fron a veterinarian.
