Adding fish and beneficial bacteria

I added 7 small fish to my 54 gallon tank. How long can I wait before adding more fish? I'm afraid if I wait too long then the beneficial bacteria I built up from fishless cycling will die off.

You periodically add more fish giving the bacteria that is there time to build itself up.

What are you still looking to add?

When did you add the original fish?

If the tank was properly cycled (do not know the conditions of your set up ), wait 4-5 days. Also, well planted tanks help cushion the period of time between addding fish while the resident bacteria build their numbers.

My tank is properly fishless cycled.

I thought all my bacteria has been built up by the ammonia that i had been adding every day during cycling. Are there different bacterias that need to grow when fish are added?

Well, there are actually 2 types of bacteria that you need to grow - one that eats ammonia and one that eats nitrites. It takes time for the ammonia-eating group to start producing nitrites for the second group to eat, and then they start to fill in as well.

As long as your tank can eat 1ppm of ammonia and 1ppm of nitrites in 12-24 hours, you're cycled. If you fishless cycled with pure ammonia and were dosing 5ppm at a time, then you probably provided enough food for a fairly large bacterial colony. This means you can probably handle a decent fish bioload right away.

If I were you, I'd test the water parameters now with the fish in and see how your levels are. If you don't have a liquid test kit, go pick up an API master kit. If you're seeing 0 ammonia, 0 nitrites and >40 nitrates, I'd say you're safe to add more fish.

It depends on how much ammonia you were adding and how much bacteria you built up during the cycle. If you used alot of ammonia then it is generally safe to add quite a large bioload right away. If you didn't develop much bacteria to start with, or are unsure, then add fish slowly to be on the safe side.

Since the adding fish thing has been covered, I'd just like to throw out a word of caution on neon tetras with an angel. I've seen 2 tasks try this combination, and both times it ends badly for the neons. I know someone will come in that they have angels and neons together and its done, but I just thought I'd share my 2 cents. Platties, hatchet fish, or other larger fish will fair better.

Thanks for everybody's advice!

My aquarium turns over 4ppm of ammonia in 24 hours. All the nitries are also turned over during this time to 0ppm.

@82nd_Airborne - Thanks for the word of caution! I plan on keeping an eye on the tetras and see how they fare. If the tetras have any trouble then I will be removing the angelfish and returning it to the pet store.

Sounds like you're golden on the cycle front then. Now If I could just get my 20L to finish cycling, I'd be a happy camper...

Enjoy the tank, and watch those tetras for sure!
