Online fish - wild caught vs tank raised - wild are better??

It's wise. There is going to be a lot you don't expect that will work in your water. You'll find out...

I used to have a fishroom full of livebearers. I moved, and the water was soft. So I switched - no more livebearers, lots of killies and dwarf Cichlids. I moved again and the water is softer, so more tetras added.

Someone has to adapt, either us or the fish...

Yep. After all this excellent education, I decided to buy fish that like my local water rather than try to control my water.

Hat’s off to @TwoTankAmin, however. He really knows his stuff AND he can deploy his knowledge in practical ways! I’ll take the easy way out.

The grandkids won’t care between the zebra danios and cardinals gets, or the Harlequins or the platties. They’ll be fascinated regardless.
