I've had my male betta fish for several months now. I use regular tap water with conditioner. The tank also has an airater included. Just latley I decided to add another fish (neon tetra) to his tank which i think caused a melt down by my betta fish. I didn't have my tetra for more than 3 hours before it died. I had also changed up the surface of my bettas tank from blue marbles to a mixture of different colored rocks. I checked on my betta this morning and he is laying on his rock not moving his gills and barley breathing. I know hes not sleeping something is wrong. I'm afraid he might die soon. Should i have not of added another fish or did the tetra bring some sickness into his tank?
I didn't add any other betta fish or put it next to any other tank with a betta in it. I only added a neon tetra.
