Fiddler Crab

Does it make a good pet?

Yes. They are a great step between intermediate and beginning pet owners. They live in brackish waters which is one of the only difficulties. Easy to feed and fun to watch around as they are active animals. You may even find them staring at you from time to time as they are very aware of little critters.
