My suggestion for next raffle is a large Royal Panaque OR a Parapteronotus hasemani (formerly Apteronotus anas(Duck Knife)here is picture of a Parapteronotus hasemani
how rare are those duck knives.. I saw one last weekend at a fish store in the same tank with a tiger ray.. Not a big tank either probably a 55 gallon.. The tip of the knife's tail was all chewed up and I actually saw the ray bite him while I was there..
good sugestion. But if they get B I G then not all members would be able to accomidate. Im starting to go with Peanut_Power's i dea of a pike raffle. Or some1 elses suggestion about some tank equipment like a filter or sumthing like that
