Freshwater aquarium crabs, away from their role as additional underwater pets and serving as decorative animals inside your tank for you and your guests to admire, remove leftover fish food and excess algae, so making them very useful. So should not you give them the best care possible?
It is important to understand that maintaining good quality water quality inside your aquarium will not only benefit your pet fish, but also other living organisms inside your tank, such as your pet crabs. The water temperature inside your aquarium should be kept between 70 and 82 degrees Fahrenheit. Also, be sure to change 10-25% of the water inside your aquarium at least twice a month.
Crabs are bright creatures, always wanting to explore worlds that are not within their reach. They will attempt to get out of the aquarium at every opportunity so unless you plan on walking your hallways searching for them, be sure to seal every crevice or opening that you think they might tinker with in order to escape.
Aquarium crabs need to have a varied diet so that they remain well-nourished. Food options for them would include flake food, dried food, pellet food, as well as frozen and live food. A word of caution when feeding them frozen food – let the food thaw before serving it to your crabs or they might not be interested as they do not like eating cold things.
Give your pet crabs lots of decor and scenery. Crabs are fond of crawling around on just about anything, so like a hamster to a rolling ball, crabs will want to explore and move around pieces of wood, rocks, or even small pieces of coral. Give them the playground they deserve so they do not get bored and try to find a playground outside the aquarium.
If your plans include filling up an aquarium with both fish and aquarium crabs, you might want to do a little homework on which species of fish and crabs may get along well with each other, otherwise prepare yourself for chaos down under. Aggressive crabs might terrorize your fish and the worst-case scenario would be that your pets might try to eat each other … survival of the fittest and all that. So make sure that your pets can live together. Also, try to introduce them to each other one at a time, so they have time to adjust to each other. Instead of putting three crabs and three fish together in one aquarium all at the same time, begin with introducing one fish and one aquarium crab – before adding additional species to your tank.
Good news: crabs have good immune systems and are generally resistant to disease, just as long as they have a clean, healthy and comfortable living environment. It is important that their swimming and living area (ie your aquarium), is clean at all times. You need to understand that their eating place also serves as their toilet. Since they can not do it themselves, you need to clean up after they excrete their waste in order for the water to remain clean.
Overcrowding an aquarium is also a big no-no, since your crabs need space and legroom in order for them to be able to roam around.
So folks, if you remember to do all of the above, you will ensure your crabs have a long, and hopefully satisfying life as household pets.
