No, the first thing to do when building a stock is figure out your GH or general hardness. Do you know this figure?

Rather than just pick a couple of this, a couple of that, the first thing to do is look up the fish you like on Seriously Fish. https://www.seriouslyfish.com/knowledge-base/

Look at the hardness they need, the temperature they need, do they need to be in a group.
Find out how hard your tap water is by looking on your water provider's website.

The look at the needs of the fish on your list. Do they all have your tap water hardness somewhere in their range? If not, cross them off the list.
Do they all need the same temperature? Organise your list into groups according to their temperature needs, then decide which group you prefer.
For those which need to be in a group of the same species, make sure your list includes at least 6 of them.

Now go back to Seriously Fish and look to see if there are any problems keeping your list together in the same tank. If there are, cross the problem fish off the list.


Finally, post the list on here again.
