looking for negative reports (or positive) before I put 2 in my cycling 75g reef tank, thanks  SignatureJohn N. Gretchen III Port O'Connor TX http://www.tisd.net/~jng3 > looking for negative reports (or positive) before I put 2 > in my cycling 75g reef tank, thanks I would never put any inverts into a cycling tank. They may not survive the ammonia peak. I hear your concern. The tank has been cycling for three weeks with live sand and live rock. This mornings test yield sg 1.021, ph 8.4, nitrite 0, ammonia 0, nitrate 0. My problems are the algae and calcium 330 mg/l level. Is 330 acceptable? >>looking for negative reports (or positive) before I put 2 >>in my cycling 75g reef tank, thanks > > I would never put any inverts into a cycling tank. > They may not survive the ammonia peak. SignatureJohn N. Gretchen III Port O'Connor TX http://www.tisd.net/~jng3 I wouldn't put an emerald in an aquarium where there will be small fish. Emeralds get huge and will happily eat a fish. The one that i used to have ate two small maroon clowns that I had. Just something else to think about. -- reefman MC Thanks for the tip reefman! > I wouldn't put an emerald in an aquarium where there will be small fish. > Emeralds get huge and will happily eat a fish.

Gretchen III Port O'Connor TX http://www.tisd.net/~jng3 Your welcome -- reefman MC I saw him catch the smaller of the two. I stopped him from killing the maroon. When i woke up the next morning the smaller maroon was completely gone. Within a week the larger was gone. I found his dead body in the crabs mouth. I'm 99.9% sure he killed both of them. -- reefman MC > I saw him catch the smaller of the two. I stopped him from > killing the maroon. Was maroon fully healthy or was it weak or dying already? This is interesting observation. > When i woke up the next morning the smaller maroon was > completely gone. Why haven't you separated them both to different tanks or at least to the sump?? > Within a week the larger was gone. I found his dead body > in the crabs mouth. I'm 99.9% sure he killed both of them. Dead fish in his mouth confirms he is a scavenger. Does not prove he attacked live fish. > I saw him catch the smaller of the two.

Here is what I found about emerald crabs on reefcentral.com: "Emerald crabs are often misidentified, and while some predominantly eat algae, others don't." - Ron Shimek What i'm saying is I saw him attack the smaller one. He actually grasped him in his claw. I then removed the maroon from his claw. I went to sleep. The next morning I woke up the smaller maroon was gone. Within a week the larger one was to. This was when I first started out with my reef. The crab has been long since gone. He was gotten rid of immediately after he ate my maroons. I'm telling you that the one I had was more predatory. Not that every emerald crab on the face of earth will be predatory. Just be careful at how large the crab is when it is bought. Buy them as small as you can get them! -- reefman MC OK, I understand. I appreciate the warning. ok -- reefman MC Emerald crabs are small, usually one half inch to 2 inches for the carapace width. Emerald crabs are usually deeper green when they are younger and eating more greens. The green fades to grey as they age and begin to scavange more. Emerald crabs have "shovel-like" claws as opposed to the sharp pointy claws of more predatory crabs. and if you look were the claw bends you'll see a red spot, thats a true Emerald crab.:) -- fishgills http://community.webtv.net/philip711/OLDIESROCKANDROLL > I wouldn't put an emerald in an aquarium where there will be small fish. > Emeralds get huge and will happily eat a fish. The one that i used to > have ate two small maroon clowns that I had. Just something else to > think about. I always considered them to be mainly herbivores and occasional scavenger. Never considered emerald crabs to be an active predator hunting for a live fish. How sure are you, he did actively hunt for them, and not that they died on their own and the crab just helped himself to a piece of dead fish? http://www.vividaquariums.com/10Expand.asp?ProductCode=02-1710&ReturnTo=/10Brows e.asp?Category=Coral+And+Invertebrates:Crabs The Emerald Crab is a superb algae eater, and will even eat bubble algae. It is very useful in keeping reef aquariums clean and free of undesirable algae. Large specimens can be harmful to small fish although this is unlikely, especially if there is sufficient algae for the crab to eat. > > I wouldn't put an emerald in an aquarium where there will be small fish. > > Emeralds get huge and will happily eat a fish.
