Thank you!!! I'm gonna scub the whole pond tomorrow (I was gonna clean it today, but as I noticed them being ill, I thought I'd wait until tomorrow when we can get the medicine). The pump and filter is off (should I remove it? As the fish is still in the same water?)

Mythelene Blue or Tricyclene, gotta remember that... oh what the heck... I'll just print your post, that way I'm sure i'll remember! Thanks a lot though! These fish means a lot to me! We had Dr Evil and Brains for 4 years now (used to have them in an aquarium when we lived in a flat), and they're my little babies. It's so upsetting seeing them ill, and I'm feeling really helpless. I've never actually had any ill fish before (except for a betta, and he died after 2 days), nor do I have any real good experience with ponds (great with aquariums... the pond came with the house, so it was kind of a hand-down... and so was Spotted Dick, he'd lived in the pond for 2 years when we got it).

At the moment the water is quite warm, as we've got hot weather, if the weather changes, I'll get a water heater (have a tiny one for an aquarium... doubt if it'll be any good in the pond).

I'm feeling really guilty too, for adding BBB straight into the pond, but as the garden centre said he was healthy, I just took their word for it... and now all the other fish has to suffer for my foolishness.

It has happened within the last two days, though... as I've been keeping a close eye on them due to the white spots BBB has. But yesterday it was such awful rain here, I just ran outside, and quickly fed them, and ran back in (also... only fed them once yesterday... poor babies!)

And today... finrot.... aaargh!
