When your oscar isn't feeling the water change...

My Oscar got me pretty bad and had given me a slight crack in my finger and it hurts a lot .
Look at the buldge on my finger
Haha old day but still love his.

I've lost track of the # of cuts/scrapes/bites/stabs from my clown loach pack. When the worm frenzy is on they don't care lol.

I have a couple scrapes and marks from fish. The worst for me would be the tip of my finger being just about removed from a dog face puffer during my saltwater days.
I had a flower horn for a while that would attack anything I put in his tank he got me pretty good a few times.

This reminds me of an old Male Blue Monkey ZZ I had years ago when Flowerhorn first came into the scene. Most aggressive fish I have ever owned... By far! When he finally dead you couldn't see into the tank because the front glass was scratched to bad. I would have to net and remove him to do any kind of maintenance. Made me bleed at least once a week. Straight freak!!
