Nutrition
Nutrition blocks cover dietary requirements and nutrition-related disease risks, drawn from professional veterinary references. Presented verbatim. (1 block.)
Aquarium-fish nutrition — dietary vitamin C deficiency (“broken back”) and iodine deficiency (thyroid hyperplasia)
Inadequate dietary vitamin C can result in a condition called broken back disease by some farmers
Iodine deficiency can result in thyroid hyperplasia
Health & Disease
Health blocks cover common conditions and their clinical signs, drawn from professional veterinary references. Presented verbatim. (3 blocks.)
Aquarium fish gill disease — parasites, bacteria, and environmental causes
Divalent ions are excreted principally via the kidney, and monovalent ions and nitrogenous excretions via the gills.
Accordingly, lesions of the kidney and gills may seriously interfere with respiration, excretion, and fluid balance.
A gill biopsy can also be performed, but the fish should be returned to water for a brief period (30 seconds to one minute) before performing another procedure.

Aquarium fish parasitic disease — protozoa and external parasites
Unbuffered MS-222 should never be used; it is very acidic which can not only damage fish epithelium but can also cause some parasites to detach from the fish.
Tissue should be examined for morphology and for the presence of parasites, bacteria, or fungal elements.
Wet-mount examination of fish tissues is crucial for diagnosis of most parasites.
