Adding Corys To A Tank?

[connorsbala]

HI there,i want some corys and was wondering how many you should add in at a time?WHen you bought your corys,how many did you add at a time?If you were to add 5,wouldnt the ammonia levels shoot right up?

I think it's all relative to the size of the tank and the number of fish you already have in there.

For example, if you have a 20 litre tank with 2 fish in and add 5 corys, you may notice an increase in the ammonia levels, but if you have a 200 litre tank with 20 fish in it, the impact may be less noticeable.

I think

Before you get your corys, check that the tank size is suitable for them and that you would not become overstocked by adding them - then (assuming that your tank etc is suitable) after you add them, monitor your levels closely.
