Anyone Know If Rummynose Tetras Are Prone To Whitespot?

My entire shoal has suddenly developed white spot. The only change is the new rainbow goby female and she's not affected.

Gawd! After I get over this I'm sticking a filter in one of the big tanks to keep it active for a quarantine tank. MTS is a pain sometimes.

Likewise. I would always use a quarantine tank. In fact, I found myself in the situation of needing both a quarantine tank and a hospital tank simultaneously - the newly arrived harlequins were in the quarantine tank when the first casualty occurred in the main tank and needed hospitalised.

I now have an old, glass tank stored up high in a cupboard which is the spare tank (in the event of a le*k - can't bear to utter that fearful word) or quarantine tank for any newbies or if I had to hospitalise a lot of fish together, and I have a smaller, lightweight, plastic, easily retrievable tank for emergencies such as one or two fish needing hospitalised.

I have one spare heater and keep two filters in the main tank so that one can be removed for use in the spare/quarantine tank or hospital tank as required.
