Hello Tiny welcome to the forum ! <img src="/images/graemlins/smile.gif" alt="" />
Dang, hate when that happens...poor fellas. The best thing you can do for them is to be sure to keep the water very clean. Take some water out every day or every other and replace with clean fresh aged water. You could add some aquarium salt to the water...start with 1/2 teasp per gallon and then you can increase that to 1 teasp per gallon.
The best and easiest way to change water without disturbing the fish is to use some airline tubing to syphon it out. This works especially well if you have a smaller size tank/bowl. Make sure the water you add is as close to the same temp as the water in the tank...but don't use warm water from the tap. If you set some water aside ahead of time and allow it to reach room temp, that should be fine.
I'm sure they will heal up well Tiny, as long as you stay on top of the water changes. This will prevent any bacteria from attacking the injuries and finrot should not be a problem...but keep an eye out for it.
All the best to you and your little bruisers...lol. Do come back and let us know how they are doing ! <img src="/images/graemlins/laugh.gif" alt="" />
