Whitspot / Protozin

[matt_99]

Hi all, will try and keep this short...

4 foot tank with stable water conditions. Fresh water is treated with nurafin, everything been fine for a few weeks.

Then a platy died unexpectadly last week. It was one of 4 that looked pregnant. Then we noticed white spot on the rummy nose Tetra. Then another platy died, that also looked pregnant. We now have atleast 4 platy fry out in the tank and hiding but living.

Rest of tank is 1 dwarf gourami, 6 peppered cory, 1 albino and 1 normal BN plec, 6 zebra danios now 8 platys and the 8 rummy nose tetra.

We took the neon tetras out and into a seperate tank as they were the only ones that showed the whitespot however the water conditions have been a lot harder to stabilise in the 20gal.

Am i best to put the tetra back in the 50 gal and treat with the protozin or will this harm the cory / fry? (will the rest of the fish likely get whitespot?)

Not sure if the platys are a related issue but we have 3 different types of platy and both deaths were different types.

All help appreciated!

Best to treat the whole tank when you have a break out of whitespot.
If you are finding it had to keep water stats stable in the 20 gallon, I would add the fish back to the 50 gallon.

With having fry and neon tetra's I would only half dose the whitespot med.

thanks we did put the tetras back in, however theyre rummy nose, not neon... i dont know what id had to drink that night!

We've now also found the male BN plec that i hadn't seen in a while is covered, so have treated the whole tank and doing daily 50% water changes.

I'm also using Protozin to treat some pimples on my Pearl Danios (never seen ore than two spots on any one fish, and they are like cotton wool balls of ~1mm diameter).

I've not read anything about doing 50% water changes while medicating. All this is going to do is dilute the meds and prolong the illness, surely?

Unless I am convinced otherwise, I shall be keeping the same water until at least Sunday, two days after the "day 6" final dose. If they still show symptoms, I will then do a water change and consider whether to try another round of Protozin, or more likely, take the infected fish with me to my favourite LFS to see what they reckon (could not do that at the weekend, fish were a nightmare to catch in main tank and got quite stressed, but now in basic QT tank).

If you have to preform a water change during a med course, you just add the correct amount of med back to water removed.
