I'm afraid some people have had really iffy results cycling tanks with those biological starters. It seems that they can really skew the readings. It will be great when you can get nitrate/nitrite kits because I wonder if those readings are a bit high. That is usually the case. That would cause Claude to clamp up a bit and be just a bit . . . off. Also, have you had any weather changes? Sometimes bettas can sense those. Or so it's been said. I'm not 100%, never been able to test it. Is he eating all right?
