Salt water tanks and sea hermit crabs?

Question

ok so i have a little 2.5 gallon tank and that would have to do until i get somethin a little better, to make that a salt water tank do you just add salt? how much? it has a filter and stuff but is that big enough for a couple of sea hermit crabs if that's all i have in there? what exactly do they eat ( i know they eat alge and stuff but if it dosent have any alge yet what else )? and how long can they live w/ out a filter?

Answer 1

Salt water tanks are something you need a real pet store person to help you with.  You buy a bag of special salt and mix it with non-choronated water to get sea water.  It sounds plenty big for underwater crabs and they can do ok on algae and maybe some fish flakes.

I like the land crabs though.  They are very good at escaping so you have to be careful.  They end up dying in weird corners and then you can't find them until they start to smell.   Mine ended up in  a greenhouse and they liked to eat bugs off of plants.

Answer 2

I didn't know you put crabs in water.  I always thought they were terrestrial.  huh.
