Accidently Over Medicated...Anyone Know How Much Damage to Fish

I have two male bettas in separate 1/2 gal containers (waiting for their tanks to cycle) that I am medicating with Maracide and Maracyn 2 for velvet.

Last night I was supposed to put Maracyn 2 in @ 1 packet for 10 gallons. I mixed the packet with 10 teaspoons of water figuring that I could then use 1 teaspoon for 1 gal of water. That would have been fine if I was fixing a gallon to use for both of them as I normally do for water changes but....I don't know what I was thinking...since it wasn't the day for water changes, I just put 1 teaspoon in each of their containers. So I actually double dosed them with antiobiotic!

I didn't even realize it until this morning and as soon as I did I did a 50% water change on both -I use spring water so that wasn't a problem. I did notice when I fed them (before I realized I had over medicated) that they didn't seem to see the food like they ususally do. I mean they swam right past it but then it seemed like they smelled it more than actually saw it and they came back over and ate it. And one of them seemed to have red eyes. Could I have have blinded them? I feel terrible. I am going to kill these poor guys with kindness!

Anyone have any idea just how bad over medicating them is? Will they recover ...assuming the velvet doesn't get them?

Thanks,

I don't think an x2 dose of anti-biotic is going to kill your fish. Keep up with 50% daily water changes (since they are in uncycled containers) and they should be ok. Usually the concern with antibiotics is killing off the biofilter, but luckily that isn't a concern here.

When I got home tonight they were both still looking the same and eating so I guess it didn't hurt them too much, thank God. Next time I will definitely slow down and make sure I know what I am doing!
