wasp Posted November 7, 2006 Report Share Posted November 7, 2006 This guy spent the night where he is pictured, yesterday it was solid coraline, today look how much he ate in one night! It is quite amazing to watch hime from the other side of the glass bite it off. His mouth is 4 little needle type things they must be incredibly strong.

land_lubber Posted November 9, 2006 Report Share Posted November 9, 2006 looks like someone chucked black paint at the back of your tank :lol: Quote Link to comment Share on other sites More sharing options...
evilknieval69 Posted November 9, 2006 Report Share Posted November 9, 2006 why would you want it to eat the coraline?? Coraline looks coolm bare tank glass looks yucky... Lol Quote Link to comment Share on other sites More sharing options...
wasp Posted November 9, 2006 Author Report Share Posted November 9, 2006 Yes it does look like a paint bomb :lol: In real life he's cool though one of the best things in the tank. There's 2 of them so double cool! Evil it's not that I wanted them to eat coraline but if there is no algae that's what they eat, but luckily there's plenty coraline so no worries. Also on glass the coraline gradually gets thicker then falls off in big chunks so this way it gets thinned out and regenerated. Quote Link to comment Share on other sites More sharing options...

wasp Posted November 9, 2006 Author Report Share Posted November 9, 2006 Another interesting thing I just noticed, look at the 2 pics. Both of the same bit of coraline, no photoshopping, but shows as 2 different colours in the 2 different pics! Quote Link to comment Share on other sites More sharing options...
wasp Posted November 9, 2006 Author Report Share Posted November 9, 2006 So they are algae grazers?? Yes. I have a 3rd one in another tank, there is no coraline in that tank but a good algae supply, and it's been living there perhaps a year or so, so they must be able to eat either or.

Duke Posted November 9, 2006 Report Share Posted November 9, 2006 Wasp what is it? Where did you get it? I like it looks cool. Quote Link to comment Share on other sites More sharing options...
lduncan Posted November 9, 2006 Report Share Posted November 9, 2006 Looks like a Longspine urchin (Diadema setosum)? Heaps of info around on their algae eating habits. They are used as an indicator species in the Caribbean for reef health. Here's a pic of mine. Came as a hitchhiker. Just popped out of the rock one day. They grow VERY quickly over a month or so it got to this size: Layton Quote Link to comment Share on other sites More sharing options...

wasp Posted November 9, 2006 Author Report Share Posted November 9, 2006 Here is some info, they are very cool. The only thing in this little article that differs from my own experience is it says they hide during the day, mine are a bit more timid during the day but still move around in plain view. Their "eyesight" is pretty much just detecting changes in light, they can detect me if I put my hand up to them & point their spines towards me. http://www.liveaquaria.com/product/prod ... pCatId=591 Quote Link to comment Share on other sites More sharing options...
