It seems that whenever I do they die
My last Betta died after we named him, though that was probably because then I was ignorant and chose an old one and put him in too small a bowl. My new Betta has a 2.5 gallon tank and is younger. I kind of want to name him but what if he dies, too? It's not just my first Betta that died, but other saltwater and freshwater fish over the years.
He has a pink body but red fins and tail and face so I think he's beautiful but naming him might bring the bad luck and kill him, too. Should I try naming him?
