I don't know what the funeral arrangements will entail (specifically burial vs cremation), or if this is stepping on toes, but in addition to the food and money, there are two things i had in mind.
#1) If you have a coral that you got from tim, frag it and pass it on. Mike (woods), that cyphastrea i fragged for you, it was from Tim. Don't worry about paying or trading me back for it. I also have an oregon tort (brown/green body with light blue growth edge) frag that is doing exceptionally well that I would love to pass on to someone with an SPS appropriate tank.
#2) (Here's the one that is up in the air). If it's a traditional burial, if it's alright with the family, maybe we could send some frag plugs with him? With messages sharpied on them or something? Maybe they don't even have to be buried with him, just given to the family. But it might be neat to have a collection of everyone's different kinds of frag plugs with short messages to Tim.
