The Puffer Forum

When soaking frozen food with Metronidazole for use as a prophylactic treatment for Puffer parasites, Seachem's Metro didn't seem to dissolve in the water so I looked it up. It turns out that it isn't very water soluble (10 mg/ml), and I've found that 100mg won't come close to fully dissolving in 1 tbs of water, even if left overnight. Seachem says to mix it into a tbs of frozen food paste and feed the paste to the fish, but most puffers are not real fond of dry food. I'm not sure what frozen food paste is, or if it would hold together long enough to be eaten.

Is there a trick to getting this medication into a puffer in sufficient amounts to be effective? Our burrfish will both eat Hakari Sinking Carnivore pellets willingly if soaked in Metro, but spit out thawed krill where I've punctured the shells and mashed them with tweezers into the undissolved Metro at the bottom of the beaker. I suspect that in the former case they are not actually getting a sufficient dose, but in the latter they are, or am I wrong?

have you tried injecting it into a shrimp?

Nope, but I was considering injecting a shrimp or an earth worm, but I'd need it to be dissolved, unless maybe a syringe with a large bore needle.

I can't remember how I did this in the past, just that it was easy. I probably just soaked frozen krill and didn't notice that the stuff didn't seem to dissolve.

Pretty sure you could get a larger bore needle into a earthworm.

Not sure how big the fish is but with mine since he is finally eating again I have been injecting stuff into the clam meat strips we have been using.
