So I am a new comer, I have had my Betta (Mozart) for almost a year, he's my first fish ever. Until going onto this website I thought they were just a one fish kind, no fish mates. After learning a lot more about Bettas I wanted him to get fish mates. I went to Walmart and got a 10 gallon tank, gravel, lots of plants, another one of his favorite bridge, and some new hiding places. Now I asked they Walmart person for 4 Corys but I think instead I now have 4 hi-fin black tetras. I couldn't even find this exact fish online and I am worried that in a couple weeks from now when I put Mozart in the tank they might harm him.
Now I have been watching these hi-fin black tetras and sometimes they are all cool and in a group, not straying too far and sometimes they huddle in separate corners and when another gets too close it's chased away. And maybe I'm just too used to the way Mozart looks but these tetras have tiny noses, and they are kinda see threw.
I know it's probably my own fault by going to Walmart but it is where I got Mozart he is a great fish. Very active and responsive.
Sorry it's a bit messy, I'm on my touch phone so again sorry.
