Just as the title says, are there some types of betta (eg: vieltails, plakat, HM etc) that are genetically more "tough" and dont have as many issues as others?
I have found in my experience that my viel tails are the ones that live the longest (and are also the largest of the fish i have had) and that crown tails have almost NEVER had any fin problems.
My halfmoons however are always TINY!
Take Sherlock (my new fish right now) hes half the size of my viel tail dispite the same treatment BUT i have noticed that out of all the fish i have had the HM's are the more likley to have fin rot / other fin issues. Are they just genetically smaller?
What about Plakats? I was reading around that most consider them the toughest "breed" of betta and that they are more resistant to diseases, have you found this to be true?
