Understanding Aquarium Sharks

hammerhead sharkSharks are not the type of fish where you would want to keep in mini size home aquarium because they can easily outgrow any tank which you initially think they would fit well. Apart from that, they are known to notoriously yank off flesh if you try to hand feed or just putting your hand in the tank during water change. Because most of the shark species, require special attention, obviously they are not the type of pet you would want swimming in your pool either and keeping them for viewing pleasure in captivity are best left to professional expert handlers in large Marine SeaWorld. However, that does not mean we should not take the effort to know them better.

Most people will often think of sharks and perceive them as a creature bound to become men’s worst enemy. Just like any other fish species, they also have the right to survive and being a predator in the sea eating mostly small fish, generally they don’t go the distance to search out human and destroy us as one would think. In fact, sharks are actually hunted for the fins and most of the time after the parts are removed, they were thrown back to the open sea and left to die. Well, you can judge for yourself whether it actually the humans or the sharks to be the enemies here and there has been a long-standing debate on this matter on whereby they deserve to be protected from such treatment.

Sharks kept in public aquariums are very sensitive to changes in water chemistry, salinity, temperature fluctuations and they are particularly fussy about having metal components that form the aquarium housing system. Filters or Protein skimmers sometimes will contain certain parts made up of alloys or metals and that will cause the fish to lose direction and dash aimlessly not knowing where to go. This condition can be life-threatening and it will wreck the whole aquarium system, injuring itself often by cutting through sharp edges during the frenzy. Apart from this problem, their huge appetite also means that the water will foul easily and that creates an unhealthy environment for the fish to live in.

In terms of breeding, different species of sharks are known to undergo different process of reproduction, with some laying eggs, some will give birth to live young fish and they have surprisingly low birth rates as well. Depending on species, generally young sharks are also slow-growing and their presence in the wild are being threatened by fishing activities that often get them caught in nets and ended up being thrown away. The fish is also highly susceptible to disease and their response using normal treatment chemicals and medications often produce poor results. In fact, they will resist any copper treatment which are often used to treat marine fish and the fish is also known to harbor parasites in their body that normally comes from unclean foods offered to them.

Again, my stand is that you should never attempt to keep and breed the sharks in your home aquarium even if it means constructing the best technologically advanced aquarium setup you can think of. Finally, if you still have the knack and enthusiasm to have something that resembles a shark, then you can even consider some freshwater shark family like the red tail black shark.

About Me

My Photo

My fascination and interest towards aquarium fish has led me to devote my time towards caring and learning about this wonderful pet.

Aquarium fish keeping is a very challenging and exciting hobby. When I first started, I never knew much or have the necessary guidance back then because none of my family members were actually a keen hobbyist. And because of that, I’ve encountered numerous failures and the worst part is having to deal with dead fish every time when you started to grow fond and getting attached to my pets. However, I persevered and took steps to find out and search for information from other hobbyist, apart from the knowledge gained and learned from my own experience and research. The blog that I’ve created here is meant to share useful information and tips about aquarium fish keeping so that new hobbyist will not make the same mistakes that I’ve made in the past."
