Saltwater Aquarium FAQ
What is the difference between saltwater fish and freshwater fish?
Freshwater fish are found in rivers, ponds, streams, and lakes. Saltwater fish, on the other hand, are collected from the seas and oceans which allow them to have a much more stable environment. They do not adapt easily to major chemical or temperature changes. Plus, since most saltwater fish are collected right from the ocean as apposed to their freshwater cousins that are tank or pond raised, saltwater fish are more expensive due to the shipping and collecting costs.
What size tank is needed for a saltwater aquarium?
Most saltwater aquariums are between 30 and 55 gallons. Almost any size tank can be used but, it is easier to keep a larger tank chemically balanced and it allows more options for fish compatibility. But, a medium sized tank is more cost effective due to the requirements of adequate equipment.
How many fish can I put in my tank?
The Rule of Thumb is one inch of fish (measured from the nose to the base of the tail) per 5 gallons of system saltwater. Potentially, you can house more fish in a marine aquarium than the Rule of Thumb allows but, most saltwater aquariums, especially new tanks with minimal filtration, lack a really good biological filtration system that can process the fish waste. This can raise the ammonia, nitrates, and phosphates to toxic level. Saltwater fish are much more sensitive to tank toxins than freshwater fish. Overcrowding can also cause territorial problems with aggressive fish. In small tanks, it is better to be safe then sorry in this case.
How Often Should I Feed My Saltwater Aquarium Fish?
Owners should feed their saltwater fish about twice a day.
Make sure that the fish are eating the food within a couple of minutes. You don’t have to feed them all of the food at once, instead spread out the length of feeding time. Also, make sure that all of the fish are finding food to eat including bottom dwellers. Stop feeding if the food is reaching the bottom and is not being eaten.
Fish in the wild look for food almost constantly, especially herbivores. They constantly look like they are grazing. Carnivores pretty much just cruise around, passing up easy meals. Herbivores have a longer digestive track than carnivores so it takes longer to digest algae in order to extract the protein required for the fish to survive. Carnivores have a shorter digestive track because it doesn’t take as long to extract the protein from the flesh of another animal. Algae that grow in your tank will provide a certain amount of a constant food source for herbivores. By spreading out the length of time that fish can eat will provide both, herbivores and carnivores with the right conditions for ample nutrition.
Can fish and invertebrates live in the same tank?
It is up to the aquarium owner to decide whether they want to do this. It should be left to the extremely novice, aquarium owners. Although there are a lot of really beautiful reef fish to choose from, some are carnivores and will feed on invertebrates or live coral. Plus, diseases like ich can be very hard to treat since the cell structures between parasites and invertebrates are similar enough that the effective treatments for ich will also kill the invertebrates.
