    Study Notes

    Fish Diseases

    • Fish diseases result from various factors, including environmental conditions, physical injuries, nutritional deficiencies, co-existing organisms (like viruses, bacteria, fungi, and protozoa), and combinations of factors.
    • White Spots (Ick): caused by Ichthyophthirius parasite affecting all fish; symptoms include small white spots that may ulcerate; treatment involves slightly raising water temperature and using commercially available remedies.
    • Tetrahymena: a parasitic disease affecting freshwater fish, no treatment available.
    • Fin Rot: bacterial infection affecting all fish; symptoms include erosion at the edges of fins; treatment includes improving water quality, feeding vitamin C-enriched food, and using anti-fungal treatment to prevent secondary infections.
    • Egg Fungus: fungal infection affecting eggs only; symptoms include fungal growths on eggs; treatment includes removing affected eggs and using methylene blue to medicate the hatching tank.
    • Malawi Bloat: possibly a viral disease affecting all fish; symptoms similar to dropsy; treatment includes offering high-fiber diet.
    • Lymphocystis: a viral disease affecting all fish; symptoms include cauliflower-like growths and white areas around eyes; treatment involves potential vaccination.
    • Overfeeding can be harmful to fish.

    Aquarium Setup

    • Recommended tank size: 125-250 liters (80 cm x 40 cm x 40 cm or 100 cm x 50 cm x 50 cm).
    • Most popular size: 60 cm x 30 cm x 40 cm, with a capacity of 57 liters.
    • Aquaria tanks are usually measured as: Length x Depth x Height.
    • Aquaria tanks can be: metal frame, Plexi-glass, or all-glass.

    Aquarium Types

    • Freshwater Aquaria: house fish and plants from freshwater environments.
    • Marine Water Aquaria: house marine flora and fauna.

    Aquarium Bottom

    • The base of an aquarium is the bottom.
    • Aquarium bed: prepared over the base, providing a growing medium for aquatic plants and simulating a natural environment for fish.
    • Aquarium bottom plants can be categorized as:
      • Rooted plants: Vallisneria, Sagittaria
      • Cuttings: Fanwort, Hygrophilia, Ceratophyllum, Limnophila
      • Floating Plants: Lemna, Riccia, Salvinia

    Aquarium Stand, Hood, and Placement

    • Aquarium Stand: a wooden or metallic structure to securely hold the aquarium.
    • Aquarium Hood: a top covering to confine fish, minimize water loss, protect against intruders, and support light attachment.
    • Aquarium Placement: should be in a location that receives maximum amount of light.

    Aquarium Filters

    • Purpose: remove harmful substances (ammonia, nitrates) from water.
    • Types:
      • Mechanical filters: remove solid particles.
      • Chemical filters: remove dissolved impurities.
      • Biological filters: convert toxic substances into less harmful forms using beneficial bacteria; categorized as UG filters, foam filters, and power filters.
    • Functions of biological filters:
      • Ammonia is converted into nitrite by Nitrosomonas bacteria, then nitrite is converted into nitrates by Nitrobacter bacteria.
      • Plants absorb nitrates.
      • Filters remove waste, dead organisms, and uneaten food.

    Aquarium Decoration

    • Oxygen supply: stone diffusers connected to an air pump.
    • Decorative toys: available in the market.
