Red Tailed Shark with Goldfish

oh that makes since, i'd forgotten that i suggested white clouds so i thought you were talking about the IR sharks. i couldn't figure out if you were talking about the goldfish being snacks for the sharks, making a snack out of the sharks or something about a snake? :) have you tired white clouds before? ime, my comet chased them around for a few minutes and then gave up because they were too fast and lived peacefully for months until my sunfish decided it was big enough and would like to taste the white clouds, i'm now out of white clouds and have one very fat sunfish that still begs for food.
 
bala sharks need warmer water and the IR sharks will eat the goldfish eventually, not to mention they're nearly impossible to house.
my favorite goldfish tankmates are white cloud minnows.
My bala shark is living in a coldwater tank with no heater and hes fine!
 
I have a comet just introduced a red tailed shark one with all red fins to my tank the comet has been chasing the red tail all over the tank. The red tail is pretty quick out classing the comet. Watched for 30 mins. Will this settle down. And will they get along?
