Welcome to our Forum!
Believe it or not, I just removed myself from a FB group both as a member and a mod. If you want a nice FB group you can join mine (linked in my sig) where shaming is grounds for instant removal and I enforce it. Wanna be rude? Gone! Wanna shame? Gone!
However, even though I have my small group I spend a majority of my time here as it is a friendly, non-judgmental environment with a vast amount of knowledge and diversity of opinions and ideas from all over the world. We can disagree with each other but we must disagree politely.
BTW, as noted, my group is a linking member with PetGuide so linking is acceptable. Linking to social groups not so linked is a violation of BF rules.
PS: IME, it is not the size of the tank that matters as much the quality of care. While, aesthetically, I prefer a minimum of 2.5 gallons, I have seen some awfully healthy, active Betta in smaller bowls/tanks. And for the first 10 years of my Betta-keeping history, the biggest affordable habitat were two-gallon bowls and my Betta all lived 6-7 years. No bloat, no fin biting, no disease. That is why I know habitat maintenance is the most important role of an aquarist. Off soapbox!!!
