Betta Turned Intolerant

Hello!

Last week my golden mystery snail passed away. Recently my betta fish has been attacking the tiger nerite snail. My mystery snail would sit in the same spot a lot before it passed. The betta and the mystery snail would sit together a lot of the time.(The picture of the betta sitting at the bottom is where it sat. This was taken two days after the mystery snail passed.) I've had the betta for more than a year and the mystery snail was almost a year with me. The nerite snail is pretty recent, being with me for a month. The betta fish tolerated the nerite snail, but since the mystery snail passing, he has started bitting. My betta also started to flare at the red gravel thinking it was the nerite snail. So maybe the color red is a trigger now? I will sometimes tap on the tank to get him to stop, but he is starting to resent me. So my fish will still like me I need some advice:

Should I move my nerite snail to my other tank? There's a lot of algae growing in the tank it's in so I would like the snail to clean it up. Its shell seems to be protecting it from the bitting, but I don't want to have a chipped shell. If I were to move the nerite snail it would be okay in the other tank, but if there is a better solution that would be preferred. My betta was never aggressive with the mystery snail, even when it was smaller. However, my mystery snail has never been as small as the nerite snail is now.

For size comparison:
Betta ~2 inches (very long tail)
Mystery snail ~ 2 inches
Nerite Snail ~dime size

Thank you for any advice!

Did the betta tell you he resents you? Come on, that is just silly.

The betta can't hurt the nerite, as the snail is inside a shell. I'd just leave him alone.

 

I can't keep mystery snails with my female bettas because they like to chew on their eyes. lol. However nerites are safe in my tank because they don't stick out of the shell as much as mystery snails. I have nerites and trapdoor snails with my snail-hating bettas but they can't do them any harm so they give up.

In other words, the snail will be fine.

Resent as in he will swim away from me or hide when he used to not to. Haha, he did not put in a verbal complaint.

Would the constant biting and flaring make my betta too stressed? I don't want him to start bitting his tail or stop eating.

 

He will eventually figure out he can't eat the nerite and leave it alone. Mine have all gone after them at some point, but they usually give up eventually.

 

He isn't intolerant. He is a predator and he wants to eat the nerite. That's all.

I have had betta splendens that learned to flip ramshorn and pond snails and suck them out of their shells in one smooth movement. Snails are food for Bettas.

Eventually, he should realize that he has the equivalent of a van full of fragrant warm pizza driving driving around the tank at all times, and he doesn't have the key to the door.
