Hi,
I have a tank that i want to fill but have no plug space for a heater so is there any chance of crabs being coldwater. I was thinking rainbow crabs.
Thanks
 
Have you considered a coldwater marine aquarium?

If you're in the UK and can get to a beach, green shore crabs are almost indestructible, and very active. You can find youngesters under seaweed and these will eat anything (and I mean, anything). Short of smashing them with a mallet or putting them in the oven, they will thrive at home. Salinity doesn't matter as they can adapt to practically anything from about 10% normal seawater through to a salinity significantly _above_ normal seawater. They laugh at high temperatures in summer, and drop ice-cubes down the back of bad filtration.

Be careful when handling them; their Latin name, Carcinus maenas, means "mad crab" and this refers to their incredible aggression when being handles. They nip, and nip hard.

You could add some rocks with beadlet anemones, which are just as hardy and will even multiply, covering your tank in red and pink splodges.

Cheers,

Neale

mmmmm....
That would be ssoooooo cool just we don't get to the sea until the holidays around here as it is quite far away. I might do that next time maybe i could add some seven spined sticklebacks as well, they do well in Salt water.
Thanks for the suggestion.
 
That is true, i didn't think of that. Since it is illegal to take rocks of a beach that must be illegal to but who would know ;) .
Thanks,
P.S-DemonMagus-How much is your PSP you are selling.
 
its not illeagle due to the fact that you can catch them on a line so you can take it home
 
I've collected fish and inverts from the beach many times, particularly while doing my marine biology degree (in Scotland rather than England though). I've also carried kilos of rocks back from the beach as an amateur fossil collector and when doing my palaeontology PhD/post-doc.

As I understand it, the law says can be summarised thus:

You cannot remove rocks from the beach placed there as sea defences, harbour walls, etc. Removing small amounts of rocks from natural exposures is absolutely fine unless the site is part of a conservation area (e.g., an SSSI, English Nature reserve, etc.) or privately owned land. Geology students do this all the time.

You cannot collect species that are protected by law such as protected species (like giant gobies, Gobius cobitis) or if they are commercially important animals that are too small to be exploited (so you cannot take an inch-long lobster or edible crab, for example).

Everything else is basically fair game. Rock pool animals like sand gobies, prawns, anemones, shore crabs, etc., are all fine. There's an art to picking species that will do well at room temperature, but bedlets, short crabs, and a blenny called the shanny are three that qualify. There is a great web site here for anyone into British marine fish. I've kept various British marines, and trust me, a properly set up native marine aquarium is easy to look after and just as pretty as a coral reef tank.
