Ha Ha....me too. It goes like this...."hum, looks like 10, no it's 20. Ok let me go outside....ok it's 20 but no maybe 10. But under my kitchen light it's 10. ok it's 10. But if I'm wrong my fish will get sick. Ok, ok...I'm doing a water change." The dialog is frustrating.
Doing well, they seem to be getting bigger day by day...and not a day goes by that I don't want to get them a bigger tank!
When and if I ever move out of my parents house I plan to get a bigger tank and plant it full of plants and let it turn into a jungle before I put them in!
I'm also looking into a plastic mesh I can use to separate the dirt layer from the sand layer...I always seem to have an issue with fine dirt particles sifting up and hanging out on top of the sand... I wonder if a dirt then small gravel then sand layer would help too...
