Thank you Perseusmom. Both of my fish are from Walmart (gasp); there are not a lot of options where I live. I had a crowntail before I got the red VT and it got some sort of disease, that made him very bloated. After doing a lot of research on here it seemed that a lot of crowntails had the same problem, so I got a second VT for the other side of the tank.
I recently put some live plants in the tank and bought two mystery snails. The two mystery snails died along with some of the plants, but now I have a nice collection of pond snails. I have since learned to quarantine plants longer than three days; it did take about a month before I started seeing baby snails. I am not sure what I am going to do with all of the pond snails, but I can't kill anything. I even catch spiders and let them outside.
