That's the ticket right there...keep them fed and they won't chase your fish (although if one lands in his lap...that he can grab hold of...he'll eat it...usually male guppies and other similar slow swimmers). I had two in my old tank...a red and blue, and plan on getting two for this tank too, although I'm going for either hoa rivers or blue moons. What I did was made ABSOLUTELY sure that whatever cave they were hiding out in got a specific piece of whatever I was feeding...usually a chunk of frozen food. They do occasionally get aggressive with pleco's...but it's more like they're defending themselves from the whip tail lol. They also absolutely require a hiding place...however you could do like I am and put the 'cave' right up against the glass...so you can always see them. There are far brighter/better colors than the reds...but if he's local and you want him, go for it =).
Hope that helps man!
