Hi, all! I'm new to this forum but have been perusing it for months in regards to my newfound hobby of fish keeping. I have my eye on a male crowntail from a breeder, but I'm hesitant to buy him because I'm concerned about health issues related to the more extravagant fin types. I've had one male halfmoon betta, and he passed away last week, but he had noticeably been less active than my shorter-finned females. He was a pet store purchase and his health might have been in decline when I got him, too. Should I expect increased health issues with fin types like this, even when I'm doing all I can on my end to ensure the health of the fish?
