Zhan et al. (2020), using DNA barcoding, found 13 different operational taxonomic units of red algae growing within freshwater aquarium stores in Taiwan. [1] [a] Staghorn algae of the genus Compsopogon may exist on aquarium substrates and can be epiphytic on slow-growing plants. [2] It can form branched, whitish-green strands up to six inches ...
Because dropsy is a symptom of an illness, its cause may or may not be contagious. However, it is standard practice to quarantine sick fish to prevent spreading the underlying cause to the other fish in the tank community in case the disease causing dropsy is contagious. [1] However, this quarantine is only effective when the disease is caught ...
In some cases the causes of an infection or disease will be obvious (such as fin rot), though in other cases it may be due to water conditions, requiring special testing equipment and chemicals to appropriately adjust the water. Isolating diseased fish can help prevent the spread of infection to healthy fish in the tank.
The Biden administration has officially determined the chemical formaldehyde poses an “unreasonable” risk to human health and should be regulated. The Environmental Protection Agency (EPA ...
Aquarium fish are often susceptible to numerous diseases, due to the artificially limited and concentrated environment. New fish can sometimes introduce diseases to aquaria, and these can be difficult to diagnose and treat. Most fish diseases are also aggravated when the fish is stressed. Common aquarium diseases include the following:
Formalin, formaldehyde gas in water, is used to as a fungicide and treatment against some bacterial infections, ciliated protozoans and flukes. Synthetic antiparasitics such as Lufenuron , Praziquantel , and Chloramine-T are sometimes used in bath treatments, as are insecticides like Diflubenzuron .
Concerns over a chemical found in furniture and flooring have put the public on alert over formaldehyde. Long-term exposure to the chemical has often been linked to cancer in humans.
Formaldehyde inhaled at this concentration may cause headaches, a burning sensation in the throat, and difficulty breathing, and can trigger or aggravate asthma symptoms. [70] [71] The CDC considers formaldehyde as a systemic poison. Formaldehyde poisoning can cause permanent changes in the nervous system's functions. [72]
