Thanks!! In an experimental mode last week, I added a male betta to the tank and so far so good. He lost some of his finnage to the Barbs, but he's been very good with the female bettas and all the other fish so far. He's more of a mellow sort male and the girls are younger and faster then him anyway. I am hoping with 75 gallons and lots of cover, there is plenty of room for them to get away if they need to. So far he's just showed off for them and not made any move to be mean at all. We'll see how it goes.
Animal Addict - I used to not be able to get pics of the fish, but I'm starting to do ok with the digital. What works for me? Just take bunches and bunches of pictures and weed out what you miss or blur.
