| | Re: What is your most regrettable fish purchase?
being highly experimental, ive had plenty. i had an mbuna tank that i threw a pair of convict cichlids in. when the convicts began mating, they locked lips and wrestled each other around the tank very violently, uprooting the fake plants, knocking some rocks over, and even breaking the filter and heater. i didnt really regret it but i didnt know it was going to get that bad either. even the pack of mbunas were scared lol.
in my community tanks i usually keep a male betta with a few females. i bought an african butterfly fish for the first time (still one of my favs) and the male betta harrassed him constantly. then when the african butterfly matured, the betta came up to pester him and the butterfly fish bit his head off...literally. didnt regret that much either.
hatchetfish have been some of the most finicky fish i have kept, and werent ever suited for my community tanks.
i regretted buying every plant i ever put in a cichlid tank.
the worst purchase by far tho was the figure 8 freshwater puffer. he was an impulse buy and i threw a pair of them in a 29gal with two adult green severums and 3 adult firemouth cichlids. i thought that if the severums ever pestered the puffers, the worst that would happen was that id get to see them puff up. i never got to see that. they were the most aggressive fish ive ever owned. they would wobble up to the full grown severums and just clamp down on their fins with their little beaks. they would even bite the tubing on my powerhead, and when they got bored of that, theyd bite the powerhead itself. they bit the gravel vacuum and my hand when i would clean the tank. after a few weeks, every fish in the tank had missing pieces of fins and the aggression/curiosity was only getting more rapid.
