I would avoid adding anything with longer fins. So, no to the Betta. Like you mentioned in your post, tetra can be fin nippers. Something to consider is that sometimes our tanks tell us we are at/ close to our stocking capacity by killing off fish. It isn't necessarily that you are a fish killer. It could just mean that your tank cant handle the additional fish. This is often the case when you have a low tech/ low maintenance set up. In order to keep high densities of fish you need to consider extra filtration and frequent water changes. I'm too lazy for this, so I usually settle for low maintenance and low stocking densities.
If you are going to add another school, they should be fish that are going to stay 2 inches or smaller. So this would mean no to the Diamond Tetra. I would consider something like Black Neon Tetra, Harlequin Rasbora, or Danios.
Alternatively you could go the route of adding in a male-female pair of small peaceful cichlids. My suggestions would be Kribensis if you are a low maintenance fish keeper. If your are doing frequent small water changes you could consider dwarf cichlids such as Rams.
Hey, you're right! OP probably should stick to the more peaceful South American dwarf cichlids (Rams). The Kribs might become overly aggressive if they form a breeding pair. In the 29 gallon there might not be enough space for the other fish to escape the aggression. I would be most worried about the cory cats. Good catch Mewt!
I think with the franken fish comment she means more like the neon ones they sell labeled as glofish. I would listen to this guy more than me by the way as I am not very experienced with freshwater.
Thanks. I just read it again and caught where I got confused. I read it as glo-light tetra instead of purple glo-tetra. Should have paid more attention.

I am confused by the Frankenfish statement. If your Colombian Tetra are red finned with blue sheen on the body, this is the natural color.
Hi FishKnight! You don't think she would run into some agression issues if she put in Kribs?
