KP Posted September 28, 2006 Report Share Posted September 28, 2006 What do bad crabs look like? Got a couple in my SPS's, but the arco that maybe receeding doesn't seem to have any in it. One of the crabs I can see is dark orange and hairy, the other looks like your average beach crab but miniture. Quote Link to comment Share on other sites More sharing options...
jetskisteve Posted September 28, 2006 Report Share Posted September 28, 2006 hairy one is probably the culprit IMHO Quote Link to comment Share on other sites More sharing options...

KP Posted September 28, 2006 Author Report Share Posted September 28, 2006 What else could cause recession from the base up? Quote Link to comment Share on other sites More sharing options...
wasp Posted September 28, 2006 Report Share Posted September 28, 2006 Quite bit of dissagreement about what crabs are bad, because all crabs have to eat something. However IMO all hairy crabs should be removed. The very light coloured acro crabs seem to be safe, and ones with a straight white line from one eye to the other are safe. The other darker coloured crabs start off safe, but some of them get bigger & more harmful as they grow. What else could cause recession from the base up?

wasp Posted September 28, 2006 Report Share Posted September 28, 2006 Tang - all those crabs you describe should be removed. That's just my opinion I know some others have had them with no problems. Chimera, sorry to hear about the TN I hope you get it sorted. If it may be related to the zeofood might pay to stop dosing it for a time, it is quite powerful. Please get back with the results when you start dosing potassium will be interesting. One thing to watch though, when I started it gave awesome colours, so, like a kid in a lollyshop I got over enthused, overdosed it, and ended up doing harm in the form of colours going drab, and took a long time to come back. Have also read that dosing must be built up slowly, a main sign too much is getting dosed is burning of the acro tips. Anyhow I've ordered a potassium testing kit from Brendan so once that arrives I'll be happy to test your water if you need that. Quote Link to comment Share on other sites More sharing options...

Fay Posted September 29, 2006 Report Share Posted September 29, 2006 And how do I catch crabs!! I never see mine unless he takes off is hairy orange shell I have had him for years, but I don't want him munching on my new little frags!!

KP Posted September 29, 2006 Author Report Share Posted September 29, 2006 I have tried catching mine, pretty quick when they want to be. My problem is that the acro he is in is stuck down so even harder. Might try and blasting him off with a stream into a net, sounds intense I know :lol: :lol: Quote Link to comment Share on other sites More sharing options...
puttputt Posted September 29, 2006 Report Share Posted September 29, 2006 Porcelain crabs (acro crabs) are fine, get rid of the rest. A while back, one type of purple tip stag I have began looking strange, and its tips began to look thin and damaged. In fact if you brushed against it the tips would crumble and fall off. Checked everything, almost decided to remove it, then went over to the tank 1 night and spied a hairy blue eyed crab munching away on it :evil: Best way to get them is to wait until dark, get a torch and a pair of forceps and grab them. They are surprisingly strong, and this little fella hung on for dear life. Put him in the refugium but when that cracked, he had to go....

I just stab or crush any suspect crabs with a screwdriver. Then it's feeding time for the trigger. Quote Link to comment Share on other sites More sharing options...

JDM Posted October 9, 2006 Report Share Posted October 9, 2006 over the last week i have removed 4 crabs from my display and relocated them to my sump, i noticed the tips of a few of my acros looking damaged, each time i noticed this there was a crab near by so out they came. are there any crabs that we want to keep in the display for a reason other than looking cool and being interesting creatures? i have seen at least one more in my display but as yet i have not been able to get him. dose anyone have a referance site that has pictures of the crabs we dont want as well as those that we do want?

wasp Posted October 13, 2006 Report Share Posted October 13, 2006 You're a girl? Good to see another one it has been pretty male orientated around here! Fresh water seems to be more a female thing, but salt is dominated by males? Don't know why, a nice marine tank is quite attractive i thought ladies would find them attractive also!

Ira Posted October 13, 2006 Report Share Posted October 13, 2006 And they can't get into the whole, "Mine's bigger than yours!" thing some guys around here get so caught up in. Quote Link to comment Share on other sites More sharing options...
