The tire track is the meaner one of the bunch. The fire eel is like a giant pea**** eel personality-wise. They should get along, and may congregate in the same cave. but there is an obvious size difference. striped pea****s are similar to pea**** eels, except a tad smaller. zig zag eels get to be around the same size along with zebra spiny eels. I'd go with the pea****s and zig zag since they are similar in temperament and size, but beware, they will get more territorial with age, like most fish.
They love pvc pipe. and with almost all elongated fish they need a good cover with no holes so they cant jump out. Be sure to have some nice smooth substrate, not sharp gravel since they like to burrow.
**** **** ****. whats wrong with roosters?
