No aquarium yet, but I think I am ready to finally get one. So my question is does this stocking work? I read that certain kinds of fish are happier/better kept in groups. Does this grouping work? Will the the green, albino and tiger barbs group up? Same with the corys, will the pepper and panda corys group up? Also, will long finned serpae tetras be ok with the barbs. Thinking all this will go in a 55 gallon tank, but how much would the stocking be able to increase if I went to a 75 gallon tank? Thanks in advance for any help and opinions.
