Nitrite down to 0.25 - more fish now?

[jackie12]

hi,
ive had my tank (rio 180) for 6 weeks and had my fish for about 3 weeks, i have 4 zebra danios and 3 platys, i did a test today and the results were, ph - 7.6. amonia - 0 ppm. and nitrite - 0.25, will it be ok to add some more fish i was thinking of 2 corys and a couple of gouramis.

Wait until the nitrite is at 0 as well. It shouldn't be long now.

Then remember that the bio-filter must expand to allow for every addition of fish, so don't add too many at once.
