[Josh jones]

Got 2 hitchhiker crabs that has been in here for like 2 months been watching them since they where baby's but now there getting big fast from what I can see there not messing with anything but I don't wanna wait till it gets bad I got a good picture of the hair one his claws are small but has long arms and the 2nd guy is a bad picture but he is purple and has kinda big claws and he is a fat one with what seems to be black stripes on he's legs should I take them out and kill them or leave I have no where to put them I do not have a sump due to I have a heavy duty hob thanks guys

First one looks like some sort of decorator crab. Second one is hard to tell from picture but looks like a xanthid crab. What do you have in your tank or plan to have in your tank? All crabs can be bad players if they do not have an adequate food source, as they are opportunistic feeders. If it were me, I would take out the xanthid and watch the other for now.
