Did you post earlier how you made your DIY root tabs? I would love to know how to do it and get some good growth on my swords!
Your betta tank looks much better. A few more wc's and it will be great. The ludwigia adds a nice pop of colour.
I have a little checkered barb that has led a solitary life. The poor wee fellow was sold to me as a cherry barb. They were juveniles, and he was mixed in with them. I haven't seen checkered barbs around here, so he is on his own. The cherry barbs all dwindled away over the years, but he is still here. He must be ancient now, so living the solitary life hasn't affected him! I hope your little pygmy cory does as well as my barb
