Well, the betta never fought anybody but those tetra were relentless with the Fire Red Dwarf Gourami
...so, I took the Gourami back to PetSmart and got 6 Tiger Barbs instead. The Betta is still in the tank for now, but that will change once I decide what I'm going to do with him. If any nipping starts to occur I will pull him out right away and into his old bowl.
I had my water tested and the pH was 7.0, the water was hard (city water, I might get some conditioning salt), and 0 nitrate, nitrite and ammonia. The tank has been running for almost 2 weeks now, and my last culture of live bacteria was a week ago with the first 10% change. I will continue to add live bacteria when I add new fish, but other than that I am going to leave it alone for now and see what happens. Water is very clear and I did my first gravel vacuum and 2nd water change today. I found a snail!!!!!!!!! Hopefully it is the only one, I guess it came from PetSmart.
Now I just need to decide what else will be going in to finish off the tank. Maybe some harlequins or danios...who knows. It'll be a little while before anything else goes in.
Lastly, I think I might be upgrading the filter to a Penquin 200 rated for a 50 gallon tank. That way, if I reach "over-stocked" status, it wont be a big deal because I will have a filter to handle the bio-load. And I really want a biowheel and the way the filter sits up a bit higher, more O2 will be introduced into the tank as the water falls in.
