Goldfish Question

My goldfish have about doubled their size in a year. I have one (a comet)that keeps sucking on the rocks in the bottom of the tank. It wasn't a problem until recently, because now the rocks get stuck in his mouth. Most of the time he is able to get it out after about 40 seconds, but sometimes I have to pick him up and pull it out. What do you suggest to prevent him from doing this? I thought about changing to a river rock, since it is bigger, but I am not sure how a gravel change will affect the water.

sry to here that about your fish, but to change your rocks the tank would have to cycle again, just keep a eye on the amonia levels, do water changes every 3 -4 days to keep it down, gl with that

Should I go with sand or a larger river type rock? Not sure what is best for goldfish.

i would go with a larger river typye rock, he wont be able to suck it up but at the same time get the food out between the stones
hope this helps

You should be able to find a smaller grain gravel that you can just place on top of your current substrate - that or just place the new larger river rocks on top - so that he cannot get to the trouble sized gravel, and so you preserve the bacterial cultures present. Kill two birds with one stone.
