|How to Feed the Sand Crab|
Studying Wild Sand Crabs
1. Understand the behavior of sand crabs in the wild.
The crabs dig into the littoral sand as the waves sweep the shore. The crabs find most of its food from what is buried in the sand. The term "sand crab" describes large (often fierce) species and small species (often carcasses) so you should match how to feed on certain crabs you have. Notice the difference between large and small sand crabs:
Large sand crabs tend to eat live or decaying prey found while digging. These animals can be smaller crabs, baby turtles, and seabird carcasses. As the large crabs dig, the crabs crave sand. This helps water and air circulate within the crab's habitat.
Small sand crabs feed on mollusks, worms, plankton, and algae. These creatures are mostly carrion eaters: these creatures conserve the ecosystem by eating decaying organic bodies that can become a hotbed of harmful bacteria.
2. Watch the natural way of sand crabs when eating.
The crabs buried themselves in the sand facing the ocean. Only the eye and the front antenna emerge outward. As the waves shrink and sweep the creature, the crab develops a second dual antenna that filters out small plankton from the water. This movement happens very quickly. Therefore, a sand crab can collect some plankton in every shrinking wave.
Most crabs can move all directions-back, back and sideways-but a sand crab can only move backward. Therefore, sand crabs should position their body carefully to obtain food from the waves that come.
3. Know the reproductive habits of sand crabs.
In the wild, reproduction occurs mostly in spring and summer. A female can produce as many as 45,000 eggs. The female carries the eggs on her abdomen until the eggs hatch, about 30 days later. For two to four months, the larvae float like plankton. Waves can carry larvae far across the ocean.
Sand crabs can reproduce during the first year of life if the water is warm enough. Crabs usually do not live longer than two to three years.
Storing Sand Crabs Inside Tank
1. Think of the difficulties when picking up sand crabs from the wild.
The creature is a coastal creature and requires high temperatures to survive. Sand crabs coexist with the waves, and it is difficult to mimic the littoral ecosystems where crabs develop. What's more, sand crabs eat a variety of foods that you may find difficulty in providing various types of food that crabs usually eat?
2. Fill the tank with fresh beach sand and sea water.
In the wild, sand crabs bury themselves in wet sand and catch plankton with their antennae. Duplicate this process by filling the habitat of crab with beach sand, then pour seawater on the sand as many as several times a day. Use any glass aquarium. Remember that sand crabs cannot dig into sand that is too dry or dense.
Try to take the beach sand directly from the ecosystem where you get the crab. The coastal sand of the place is likely to contain the insects and microorganisms required by the crabs.
Sand crabs naturally gather in the shoals so it's okay to keep some sand crabs in the same tank. Remember, however, that large crabs love to eat smaller crabs.
3. Recharge the tank with seawater regularly.
Homemade saltwater cannot work well; The water should contain algae and plankton. You can buy plankton, algae, and seawater for the aquarium at the aquarium and ornamental fish shop. Remember that this equipment can be expensive.
Understand that this way is intended for short-term experiments in studying the behavior of sand crabs. It is not necessary to keep sand crabs as pets in the long term and sustainable. If you're just trying to learn sand crabs in a short period of time, try to return them to the wild when you're done.
Consider choosing a recluse crab.
Sand crabs are tough and often almost impossible to serve as pets. If you are looking for crabs that are easy to maintain and feed, choose the ascetic crab. Do the research, make habitat and keep the hermit crab.
Aquarium ascetic crabs grow by eating all the food, from algae and leftover fish to beef, eggs, and vegetables. In the wild, famous ascetic crabs eat foliage, fruit and even wood. You can also buy hermit crab food sold on the market that resembles the crab's natural food.
