Is Fish Mox (Amoxicillin) Safe?

Is it safe for corals? Thanks in advanced.

I would be surprised if it was, but maybe @Humblefish would know.

I think not too but would like to know from experience reefers.

I've never actually tried it, but IMO any penicillin based antibiotic is a no-go with corals/inverts.

I have no idea. Sorry.

IM not sure why amoxicillin would be toxic to corals (itself) - but Im also not sure that I would want to treat a tank with an antibiotic due to bacterial death, etc and risks of changing parameters. There are lots of articles on the use of doxycine/tetracycline/erythromycin and chlomamphenical safely on corals - for RTN. Why are you wanting to treat with amoxicillin in the first place?

Here is an article treating 'white band disease' on acorapora with amoxicillin and other antibiotics:

For fish sick and I can't catch the fish out...I am not going to use it in my reef tank any way. Will try other way safer, and the fish not expensive than my corals. Thanks.

You can try a fish trap to get them out.

. Good luck.

Ha ha, I did try it for a week..the sick fish never get in...

But last night it looks better after I put some garlic in the food, hope it make it.

One suggestion - if you put some rocks around the trap so the fish doesn't realize its a trap - it sometimes works better. You Can also try to medicate the food...

FYI - I called Thomas Labs - that Product is not a problem for Corals or inverts - BUT its not necessarily recommended for a display tank with corals/inverts.

Good to hear and thanks. I google somewhere, a guy try to help a sick anemone with this product in his DT tank.
