Will I be Overstocked?

[MJC8719]

I have a 29 gallon tank that is nearly done cycling and these are the fish I want to add:
Have:1 Neon Swordtail, 1 Red PLaty, 3 Ottos

Want to Add: 4-6 Albino Cories, 7 Neon Tetras, 2 more platies or mollies, and maybe some kinda dwarf gourami

With all of these fish will I be overstocked at all. I currently do 25% water changes once a week and have a Whisper 30 Power Filter.

And one more question. When I buy the cories is it going to be better to buy them in two sets of three and put three in each week or just put all six in at once. I am afraid if I do this I will overload the system.

Thanks for all your help.

Are you going to have female livebearers, or just the males? If you have females, you'll need some plan for dealing with the babies, and with the mix you have, you likely will not be able to sell them to the LFS, due to the potential for mixed breeding. You won't want all the babies to stay in the tank, as they will quickly over populate.

Otherwise--should be okay. Not a ton of fish, none that get really large. I would get the cories in pairs or trios until you have the desired number. Putting in more may indeed be too much for the system. Ditto for the neons. While these fish do best in the larger groups, having them in a small group until the system adapts is much better than causing a spike.
