Alright, hopefully everything will be in by the weekend so I can try again. My new guy was the sweetest thing, and he turned mean in the 10 gallons. He's in 5 gallons now, and he's flaring at me, which he never did. The cory has almost no cover right now, and he got bit, but I can`t see any damage, and after I took the betta out he was midswimming around again within a few minutes. I kind of need to put someone in the community, can a male and female share water or are there some hormone things to worry about?
It may take him a while to get used to the company. When I first added my girls they chased the cories, tetras and shrimp for a while before settling down, even though they'd been sharing a tank with a ghost knife at the shop.
Be warned, though, it may take days, or it might not happen at all. :(
Is some chasing normal when adding a betta to a community? I tried to put my new guy in with the pygmy cory, but he kept chasing him around like crazy.. I'm going to hold off on trying again until I get more pygmies and my plants ship in so they get more cover. Will the chasing usually die off?
