New fish in newly cycled tank

Sooo, I finally got my tank perfectly cycled after almost 2 months. Its a 20 gallon tank, and I brought home 6 cardinal tetras, 3 panda corys, and 1 chinese algae eater. This was yesterday. My question is: because I'm so impatient, is it too soon to get some more cardinals just 24 hours later? Also, I know the whole inch/gallon stocking rule can be stretched in some cases. How about for a 20 gallon, small tetra/cory species tank?

Ooooo I sooo know what you're going through! I believe myself to be a patient individual, but I'm really fooling myself

If you can... wait a month before adding anything more. A newly cycled tank is good but let the current population establish itself and see what that does to your waters before adding anything more.

Delayed gratification is very good in this case. Plus... if you add more now, you won't be able to add anything else after that so I'd let the fish get comfy, and your mind study the tank for a while... you'd be surprised: you may change your mind on what to get in the end!

I had to be the one so strait fwd to you: But Cardinals are one of THE most sensitive fish to a new tank and I'd strongly suggest not to get any more of them for few weeks.
I also thought differently before Thanksgiving and started stocking my 55g with Cardinals - Lasted less then 1 week before all were dead, personally I'd never put Cardinals in non- established tanks ever again and I can only advise anyone else not to do it neither. I didn't wanna believe it and I paid the price and it wasn't cool to watch at all.
Let your tanks establish maybe 2-3 mos stock the other fish you want meanwhile and the add Cardinals at the very end.

One inch of fish per tank gallon. That's the rule. Live and die by it! Hehehe... just kidding... we all break it!

If your cardinals reach 6 inches each, start running! LOL!

As long as you don't break it too much, you should be fine provided you keep a good eye on your water params.

It has been stocked for 2 months with a bunch of gouramis; I just traded them yesterday with the approval of my fish man (not a chain store) for the fish I have now. So I do hope they have a fighting chance.







Ok, so if I should stay away from buying more fish for a little while. It would be ok to add maybe 1 or 2 live plants, right? or no..

Yea no the 1g/1fish crap... toss that out of the door.

There's a few things you wanna keep in mind when stocking a tank:
1) Different fish like different area's in the tank, eg top, middle or bottom
If you get 50 fish that all occupy the top naturally - You will have a problem; if you get 50 fish that some live up top, some in the middle and some on the bottom (like your cory) then you won't have a problem
2) If you have a 20g with 0 plants I'd suggest less fish; if you have a heavily planted 20g you can allow more fish as they can hide and get out of one another's way if they'd like to
3) Chose fish that are similar in behavior. Like your Cardinals are peaceful fish, don't mix these with a active or even aggressive fish, that'll just stress them out and make them die quick.
Last but not least, obviously you wanna add fish that'll thrive in your water, in your case judging from the Cardinals I assume you have soft acidic water - So chose fish that like that

You started with Tetra & Cory- Do you wanna keep stocking various Tetra schools or WHAT kinda fish do you have in mind?
There's Hachets that would go along and pref the upper part of the tank. I'd def suggest to stock the Cory to a group of at least 8, if they're less then that they tent to be skiddish and not really develop this real awesome to watch group behavior.

Gosh since you're assuming having the same water then me I could name a ton fish now...but like I said, keep the 3 ideas above in mind and then its up to what YOU like. Shop the store see what 'looks' good to you, write down names and do reseach at home or ask on here how well they'll fit in the tank (pls don't listen to the sales guys at stores, more often then not they have NO IDEA and are just THAT a SALES person).

That should call for some more bacteria in your tank - Just hope its enough and I'm really wishing you the best, it may work, why not!? Chances are you might be more lucky then others, let's hope for that!

Plants, you can add plants any day of the week - The more the better

Right, I'm aware of utilizing all tank levels.. my plan is to complete this cardinal school, add an upper level, (cloud minnow, bloodfin tetra, something of the like) complete my corys, and have live plants. Since I should wait on completing my schools, maybe I can get ahead on the plants?



Ok so plants are a go... yay! Now I have something to do :]
Thanks for the input
