Hi I'm new to keeping fish but yesterday we got 4 penguin tetras to start and Apparantly I can add some more fish in a week. I've not fed them yet, planning on feeding them tomorrow as advised but some people say after that feed every 48 hours and some say daily, what's best ? Also need to do a partial water change in a week, what's the best way of doing this ? Thanks
Did you cycle the tank before adding the fish? Please have a read of this. If you didn't then you'll have to do a little extra work to make sure the fish stay healthy and you won't be able to add any more for a few weeks. Have you got a water testing kit? How big is the tank?
Usually small fish are fed every day once they have settled in, but if the tank isn't cycled then I'd hold fire for a couple of days.
