Fish sizes
Okay I have decided to get 3 more head and tail tetras, along with 3 more rummy nose to bring those species up. My question is this, my head and tail are bigger now, how do I go about finding ones that are roughly the same size, or will it matter?
After what happened with the cardinal tetras, I learned a valueble lesson that I don't want to repeat. Time to bring up the same species.
