The tank has the 3 sick angels and the pleco in it, they all came from the same tank. The tank has only a few handfulls of gravel, I put a large piece of wood in there for the pleco as well as a tunnel/pipe for him to hide in.
I cannot get to a LFS as I live in the middle of nowhere , so I only have a few thing with which I can treat, until I can next get to town.
I bought the Tonic ,as mentioned before, on advice from a store in Auckland.
I have used it befor for white spot, and it worked on the infected guppies.
I also have White spot Cure, Cure Ex & Tonic salt.
