Some people believe that fish do not have the cortex to display distinct personality types. I used to be one of these people.
Until I got Goldy
My female Aphyosemion australe
She is really driving me crazy
If there is any situation she can get her self in trouble with she will, while other fish hide from obvious danger like the gravel vac she just heads in full speed ahead!
She some how swam up into my DIY water polisher and I mean she didn't just get sucked up by accident, she found a small opening and went for it! ( now put panty hose over the intake)
she almost always gets sucked up in the gravel vac.
When I put co2 in she chased the bubbles on the bubble count and the diffuser for at least an hour.
Just now I had the pump turned of to feed live food and she swam up and into the lily pipe. I didn't even realize until I turned the pump on and she came squirting out

!
Right now she's hanging out near the surface, no visible injuries but not lookin so good. It could be a lack of oxygen from being stuck in the pipe or some internal injuries.I hope she survives I may train her to eat from my hand.
Any one else with fish that make you want to tare your hair out?
