When Can I Add More Fish?

[Louise21]

Hello everyone

We have a 64L tank that has been up and running for about 6 weeks now. After about a week, we added 2 guppys, 2 swordys and 2 mollies along with a corydoras catfish that we had in a previous tank. One of the guppys and both mollies died. Today we have added 4 neon tetras.
Ive only just discovered this forum today so didnt know anything about fishless maturing of the tank.

Just wanted to know how long you think we should leave before adding any more fish, its just so addictive wanting to add more interesting fish but obviously you cant add them all at once or add too many!!

Also do you have any recommendations of any interesting types of fish we could add.

Many Thanks

Hi Louise and welcome to the forum

Don't add any more for the moment - your filter may have grown enough bacteria to deal with the fish you had in there before (5 weeks since adding fish) or it may not, but even if it had it needs time to grow more bacteria to process the additional waste from the fish you have added today.

Once your tank is mature you should leave at least a week between adding fish - personally, I leave at least 2, and do tests to check the water too.

Have you got a test kit to test your tank params?

Also, what size is your tank? And what filter do you have? Because those things are important in how many fish you can have.

Yeah we have some of those 6in1 test strips and also a separate test for NH[sub]3[/sub]. We tested for NH3 and it showed up very little if none.

The tank is 60 litres. We have an interpet internal power filter PF2 for tanks up to approx 90 litres.
