What Next?

[OLLYC]

My 56 litre tank is finally up and running and yesterday I added 3 Zebra and 3 Leopard Danio's, all of which seem to be doing just fine.
Temp is set to 25 degree's and am going to do a water test in 6 days.
If all goes well, I was wondering how long I should wait to introduce a new species of fish and what people would recommend.
I'd love to add some guppies but I don't want hundreds of fry in my tank either...
Any suggestions?

have you cycled your tank?

If I were you I'd check your water everyday, new filters are fairly sensitive, so you might see an ammonia spike which would need water changes to keep it at a low level.

have a read of the link in my sig 'whats cycling' which should explain it all to you.
