Hahahaha!!! I know this well!! Jello can jump SO high and the first him he did it He CLAMPED down on me! He also bit me when I was hand feeding him once, (Never did that again) Took my like 5 minutes to calm down LOL.
When I feed Angel, I have to quick throw the pellets in before she jumps! If I let her, she'd jump out of her tank! Luckily, she has a very secure cover!
None of mine really jump.. When Freddie bit me my finger was only like an inch above the water. I frequently leave the tops open or off on my tanks during the day (for better air circulation) and I've never had a suicide attempt.. not even in the 1 gallons
Okay, so he totally attacks. Lol! I can't even put a finger in there. He's like a shark. What happened to my sweet puppy fish!? He doesn't even flare and yet he was all 'om nom nom nom' on my finger! It didn't hurt and I made myself leave my finger in there thinking he'd get bored. Nope. He just kept getting more distance and hitting me harder. LOL! Do they ever like, grow out of it?! Hehehehe.
The girls in my sorority will follow my hands around their tank when I'm doing somehting like moving a plant but thankfully no one has bit me yet. Dallas is the only one who jumps out of the water though I'm sure the others could be convinced. My males are all just lazy turds.
I actually used to have a slight fear of fish I guess. Could not STAND to touch one. I have no idea why, I grew up fishing and cleanign my own fish. But having my Bettas cured me of that. First day I had Ringo he got his head stuck between two rocks and I had to save him. The girls have no fear and will swim up against my hands, and Flare lets me pet him :) Razzi is the only anti social fish. He is a little skittish and flares up at the eye dropper I used to feed everyone frozen brine shrimp.
Thats good to know my daughters fish Sarah (hes a male dont try to tell that to a six yr old) tends to follow us all over the tank but lately hes taken to nipping at her fingers when she puts in the food so far it seems like hes just saying hi but ill have to keep an eye on it. I am just thankfull he hasn't taken to jumping trying to test water with a fish nudging the test tubes is hard enough. Of couse he might not jump because he knows the food goes in the feeding ring and that's where hes waiting when the lid comes off.
All I gotta say is.. I didn't know they could bite so hard!.. I mean it didn't hurt but if Freddie were the size of a dog I'd be missing a finger! I don't think I'll ever be brave enough to hand feed them.
