my sister has an angel which after looking on the net seems to have some form of internal parasite.

what is she best to treat the tank with.

She has already lost one angel in exactly the same way rest of the tank is tetras.

Angel just hovering in the back of the tank won't eat started with a wound on body which got bigger. Wound has now stopped getting bigger.. She treated the tank with melafix when the wound appeared she thought the angels had been fighting but they were a mated pair.

Now looks like has weird pimples on it.

Definately not white spot too big.

Today started breathing rapidly and gasping at the top.

this is what happened to the other angel before it died.

Please help.

Furan2 - full course (all 8 capsules) - will nail everything.

Remove fish from community tank to treat him first though.

Prazi (think thats what you call it) is used to treat internal worms.
