Personally not worth it for a small tank. They cost so much! Unless you find one you can use for a 10gallon and your next tank.Fishywife said:Hmm. So upgrade tank in hurry then. I have a 3.5 in ax in there. I figured a 10g would do him for now. He was sent to me by accident with a shipment of micro worms and vinegar eels. Lucky I had a tank spare.
