....has she broken any tank heaters?

I've been bitten by fish before and had wounds to show for it that is awesome!

No she hasn't broken her heater. She did catch my thumb one time.

Oh, thought for sure she'd taken out a heater or two with all that activity....anyhow,I've had a few cracked heaters as a result of various fish of mine knocking them against the glass.

I'm just getting into the hobby, but I know it's a lot of fish keepers who've been doing this for decades and have encountered some aggressive fish. If you are, or have had an fish that's really aggressive who's the worst? Let's start to talk. Post pics too if you have them!

The fish that did the most damage until I moved it was a target puffer, he was taking chunks out of fish 5 times his size over night. Most aggressive was probably an auratus. For their size, they’re as mean as anything
But if I had tank mates with him, I would say my fahaka was the worst for potential damage and aggression
