I am not terribly impressed with that calculator - it gives some pretty inacurate results sometimes, and does not take into account additional factors like plants, water changes etc... And the compatibility part isn't good either - aparently i need at least 9 black phantoms for them to be happy in a school (9 BPTs isn't a bad number, but not the minimum) and that they are too aggresive to co-exist with my cherry barbs. Not so! They're the most timid fish I own. IMO 7 pristellas, 9 black phantoms, 6 zebra danios and a dwarf gourami is too much for a 20gal in both bioload and space issues. Anyway, we are going a bit of topic here and that is for another thread, so I'll stop.

I think bump all the schools up to 5-6, and maybe a dwarf gourami. They would be pushing it though.

I'm going off the topic here too so I'll keep it short - thanks for the comments, and those concerns will be addressed in the near future if they do make sense. I do collect everyone's feedback. Perhaps we can talk more about it on the right thread.
