[40 Breeder setup]

You are basically just going to be increasing the % of water you need to change. Plants, fish, all are going to contribute to the load in the tank and lead to OTS if you don't change enough. So let's say you add the others, I would bump it to 50% WC instead of 30 just to avoid any issues.

That sounds perfectly reasonable. Thank you so much for taking the time to iron all of that out for me! I was a little concerned but it sounds like it will make for an awesome tank without worrying too much.

This is the AQAdvisor for your tank as it stands.

I don't think you *need* to add 5.  I would add 4, but! you do have room to do so.

Temp and everything is perfect for them as well.

Edit: With 5 Corys it puts you at 63%, so you have room for 3 or so additional fish. Maybe 3 Gourami?

That seems pretty reasonable. It sounds like with all the fish I listed it would only be slightly overstocked, especially considering the ember tetras are pretty small. Would it be safe to assume that since it's heavily planted and is using a canister filter I should be good to go? EDIT: I should also add that the guppies are all males so they will not be making additional fish. They are also about a year and a half old so I don't expect them to live too much longer.

Second thing, is going to be what temp you're running things at, what species of cory do you have, are

The tank runs steady at 76 degrees F and the cory that I currently have is a Julii Cory. The other five that I am looking to introduce would also be Julii cory's. If they do breed it won't be a big deal as I have some other tanks I could move them to if they make too many.

Hey everyone!

I have a 40 breeder that I have had setup for a while but it's time to introduce some new fish. Currently I have roughly 5 otocinclus catfish, 1 corydora catfish, 3 guppies and one bristlenose pleco. Along with that I have at least 100 cherry shrimp. I am thinking about introducing 4 dwarf gouramis, 5 more cory catfish and 8 ember tetras. The tank is heavily planted with a fluval 3.0 light and a fluval 307 canister filter. It also has co2 running somewhat heavily. The tank has been setup for several months and parameters are all good. I typically change about 30% water every two weeks. Would my tank be considered overstocked with the new additions? Is there anything else I should be worried about? 

Cheers and happy fish keeping!

It sounds like adding dechlorinator would be an easy fix if you are not including it already. I would even suggest doubling up on doses as it doesn't appear to be harmful at these levels.
