Again check with your supplier for compatibility and feeding requirements. When purchasing plants, make sure that they are true aquatic plants. Live plants should be pruned weekly. Dead or broken leaves should be removed daily. A live plant aquarium will require the same basic equipment needed for an aquarium containing fish. Algae is a pest that will cause damage or even death of the coral. Keep the algae as controlled as possible by scheduled and routine cleaning of your aquarium. Bubble coral may also get flat worms. These worms are easily spotted and usually appear as circular spots on the coral's vesicles. They are not a cause for alarm and usually do little damage if any. They require a water temperature between seventy five and seventy nine degrees Fahrenheit, a P.H. between 8.2 and 8.4 and a salinity content of 1.020-1.024. As you can see, there is very little wiggle room associated with these measurements. It is extremely important to check the levels daily, or the results could be costly. Live plants are highly recommended in new aquariums as they will help to generate the good bacteria necessary to reduce the amount of ammonia in the tank. It is a good idea to test the ammonia and nitrite levels before adding fish to the aquarium. Begin by adding only three to four small fish. A general rule is to wait another thirty days before adding additional fish, because that is the incubation period for most fish illnesses. Their behavior will vary, but as a whole, the catfish is an entertaining addition to an aquarium. There are group and schooling catfish that get along well with each other. There are also loners who always stay away from their neighbors. Catfishes are the ideal candidates for community tanks because they inhabit niches and shelters on the bottom not occupied by other aquarium inhabitants. It would be irresponsible to attempt to house one of these creatures, unless fully educated on their care needs. Sand sharks adapt the best of all sharks to a captive environment. The types of aquariums that house these very large fish are usually public state supported aquariums. These facilities have the resources to build large enough tanks to house the sharks.
