2 Cories Dead - In One Night?

[Fishkeeper2004]

Well I went to wharf aquatics (the big-talked about place in the UK), and purchased another three cories to add to my group. The other six cories were fine, but now since the new ones have been introduced two have died, and one is missing the top of its back tail.

Water levels and everything are fine, the only odd thing I found with the dead cories is they both had one white cottony dots on there left side fin, could this be a problem, or just naturally there?

Sounds like a fungal infection. Are there cottony white dots on any of the other fish? if so then you are going to have some problems on your hands. If you see more cottony white dots you are going to need to medicate the fish. Remember if at all possible with new fish try and quarintine them first so any diseases they might have from the lfs are not transmitted to your population. I have heard that melafix can work in such instances, I believe it is from a company named Aquarium Pharmacuticals. But as in any medication READ THE LABELS before putting any meds into the tank. Cories often have trouble handling strong medications. I am sorry to hear about your losses

Thanks for the reply, no other are displaying symtoms but im going to treat for fungal infection anyway. Hopefully this will cure any disease thats it the tank, im annoyed as my tank has only been setup and cycled for around 2-3 weeks.
