the update is that i went to my local pet store and lfs and neither had formulin but my lfs did have protozin so i bought it. unfortunately when i got home it was too late for iain, one of my blue rams
he now rests in a rennie tablets box filled with woodshavings for my hamster, and will be burried along with ceasar who rests, ironically, in an aquarium salt box filled with woodshavings.
i am fast beginning to think that rosie, another blue ram, may well be resting, again ironically, in the protozin box along with them
however, i did a large pwc and vaccumed the gravel vigourously and have added the protozin. i will be continuing this medication for 6 days and just have to hope for the best now really. i bought a surplus amount just incase.
thanks for your help everyone. i really appreciate it, and i will keep this post updated with the final, and intermediate outcome
