The rats I get (frozen) are 40g. I get them from Petco so limited selection. Maybe I'll try to find a different store that has them a bit bigger or start feeding every 5 days till I can go up a size.
Won't do the double feeding thing. Also will not mix prey items, figured that would be a bad idea, but hey that's why I use on this forum.
I'm not concerned about packing on the weight, just not looking to get my hand bit when I reach in the tank cause he's a pig and hopes my hand is food.
