I am planning for stocking a well-planted 75 gallon community tank with a Fluval 405 (so a little extra power there). It is almost through cycling now and I will do this gradually but am having trouble determining what might be too much (I have seen so many different ways to calculate this). Here is what I was thinking: The small fish would be: 10 platies, 6 zebra danios, 6 corys, 6 otocinclus. The 'big' fish would be: a pair of dwarf gouramis (~3") , a pair of pearl gouramis (~4"), and a pair of angels (~6"). I would get small angels and let them 'grow into' the tank. These would be the last thing I added. Is this too much? I would like to plan on water changes every other week (barring problems).
