The local Petco has been tempting me with their pretties since the new location opened. Seen quite a few cheap koi although they've almost all had obvious blue marbling and the ones that didn't were either scrawny young males or female. I'm really hoping to find a nice male koi plakat and maybe split a 10gal with a pretty butterfly
I'm not quite the most knowledgeable on bettas inparticular, so I have a question before shopping: Are there any tail types that are unhealthy? For example, ones that weigh the fish down too much and often cause biting I'd certainly not want to keep
