I hope this isn't a stupid question. I haven't really been able to find an answer anywhere. Right now I have 4 Tiger Barbs and 2 Albino Tiger Barbs (among others). Since both of these are Tiger Barbs, does this count as 6 Tiger Barbs total? I know they do best in groups of 6+ and everyone seems to be getting along fine. Wasn't sure if I needed to have 6+ Tiger Barbs AND 6+ Albino Tiger Barbs, or just 6 total.
