These 2 are both only 1 inch, and I know that EVERYONE thinks that my fishkeeping practices are terrible, but I have been watching this female for a while, waiting for her to give birth. The reason I have trouble with this is because her mother gave birth in a 10g after I got her home from the pet store, and there were hardly and hiding places at all, but I still ended up with 8 surviving to adulthood. This tank has more hiding places (yes, I know the tank is smaller), but none survived? Fine, but thanks for crushing my hopes by eating your babies, dumb fish...
