These girls aren't too happy. I noticed the healthier of the two started to go downhill this week and I checked the airstones and they calcified over so I had to remove them and scrap them off to get them to get air to flow them through again. She's starting to perk back up a little bit. The other has always had a stunted growth but she's trying. Didn't have the heart to remove her but at this point she's just taking up space for the little she is going to produce
