Right, the last time I was at the Anaheim show, I got some confusing info about croceas being much easier than derasas and needing less intense light. All the while there was a large aiptasia staring at me and I couldn't stop thinking "why don't you nuke that thing"... Left with no clam, but I'll spend more time examining the individual clams next time. Show is in 2 weeks, so we'll see!Yeah, I would only order a clam from someone I trusted or had a really good track record of providing healthy clams. Also, John has given some weird advice about clams that seems contradictory sometimes, but you can easily spot the healthy clams when he’s at shows. I have two croceas that I bought from him last year and they’re doing great. Sometimes I ignore the people selling the animals and simply pay attention to the animals themselves, they’ll show you everything you need to know.
