My son will be studying marine biology or ecology at Texas A&M Corpus Christi, and we visited the campus last weekend. Of course we went searching for marine animals and shells...we came away with a few lightning whelk shells that were empty, until we got home and the next day realized all 3 had hermit crabs in them! My wife insisted we go buy them a tank immediately, so now we are set up with a 20 gallon long saltwater tank...so I guess my hiatus is over lol! But I'm definately keeping things small and simple this time.
The tank is fresh so not much to look at right now, but the crabs are happy!
