Need help

[Fishie20]

A week ago someone must have taunted my betta and now he is afraid. He runs from me and it is frustrating. He use to eat from my hand and blow bubbles all the time. Now he sits at the bottom and swim off fast if you gets near. Doing so he has snatch part of his fin off. What can I do?

First check the water chemistry. Check for ph, no2, no3 and ammonia. Do a big water change. Make sure he has places to hide and feel comfortable in the tank. How long has the tank been established?

It won't help to post the exact same issue in more than one thread, spreads out the info you are given too much.

Hi Fishie, maintain good water quality, with a few hiding places, the fin will regrow in time. PJ

it's more likely to be poor water quality than someone spooking him.
test the water as suggested by nik_n and do big daily water changes every day for a week. make sure new water is free of chlorine/ chloramine before it's added to the tank.
