# Ich - The fish parasite Ichthyophthirius. The main symptom of infection is small white spots on the body of the fish, like grains of salt. Also called White Spot disease.

# Incandescent - Artificial light source produced by an electric current passing through a wire inside a vacuum, heating the wire to high temperatures to produce light. Compare Fluorescent. Only five percent of the energy output of Incandescent lighting is light, while the remaining 95% of the energy output is heat.

# Infusoria - Microscopic or minute animal life which commonly occurs in water containing decaying organic matter. Includes paramecia, euglena, desmids, rotifers and others. Cultivated as food for Fry and small fishes.

# Instant Cycle - To Cycle an aquatic system using bacteria (Biofilm) from an existing system, or the commercial product Bio-spira.

# Internal Filter - Any filter mounted entirely inside the tank. The Sponge Filter is the simplest example.

# Inverts - Invertebrates. Animals characterized by a lack of a backbone or internal skeleton. May have an exo-skeleton or shell.

# Jump Start - To accelerate or bypass the initial cycling period of a newly setup tank by adding a filter, filter media, gravel and/or water that has been running on an established tank.

# Jumper - Said of a species or specimen that tends to jump out of the aquarium.

# K - Kelvin - Temperature scale used to designate light intensity. For freshwater 6400K-10000K is optimum. For marine 6400K - 20000K is optimum.

# KH - Carbonate Hardness. A measurement of the amount of dissolved carbonate and bi-carbonate ions in water. Expressed in degrees of hardness on the German scale (º dH). One degree of hardness equals 17.9 PPM. See Buffering Capacity.

# Killifish - Egg laying toothcarps. (Compare Livebearers). There are two types of Killifish, the Annuals and the non-Annuals. Annual Killifish inhabit temporary bodies of water that completely dry up during part of the year. These fish have a short lifespan and rapid growth rate, reaching maturity within a few months. They lay eggs that remain dormant until the conditions are favorable for hatching, when the rainy season returns. Their eggs are incubated by aquarists in a special way to imitate this (see Peat). Non-annuals have a longer lifespan, but most also have the ability to lay eggs that can survive a short dry season.

# LFS - Local Fish Store.

# LPS - Local Pet Store.

# Labyrinth Fish - Fish from the family Anabantoidei. Characterized by a specialized respiratory organ, the labyrinth organ, which enables the fish to obtain oxygen from the air, allowing it to live in water with low levels of dissolved oxygen. This family of fishes includes bettas and gouramis.

# Laterite - Iron- and mineral-rich soil material, a layer of which is sometimes placed below a layer of gravel in the Substrate of Planted Tanks to provide plant nutrition.

# Light Hood - The cover of an aquarium which contains the light fixtures for illuminating the Tank.

# Lip-lock - Two fighting or courting fish grab each others’ mouths and in this position continue to wrestle one another. Lip locking during fighting can be dangerous as it can result in torn or damaged mouths.

# Live Rock - Calcium carbonate skeletons of corals or other calcareous organisms colonized by beneficial bacteria and micro and macroscopic marine life that live on and inside it.

# Livebearer - Live bearing toothcarps. Species of fish which carry their offspring internally until birth. Common livebearers are guppies, mollies, and platys.

# Loricarid - The Loriicaridae, or sucker-mouth catfish, is a huge catfish family whose members include the many Plecos which are very popular with aquarists.

# MTS - 1. Malaysian Trumpet Snail (Melanoides tuberculata). A cone-shaped, freshwater snail which burrows in the Substrate and bears live young. 2. Many Tank Syndrome.

# Mantis shrimp - Common name for predatory marine crustaceans of the order Stomatopoda. These crustaceans have powerful, modified appendages which they use for defense and in subduing prey. The ‘smashers’ have calcified, club like appendages, while the ‘spearers’ have sharp, pointed appendages. Often seen as pests, they are known as ‘thumb-splitters’ and for their ability to break aquarium glass, but some species are prized for their attractive coloration.

# Marine - Refers to a saltwater aquarium or environment.

# Marine Rotifer - Brachionus species. Live food cultivated to feed marine Fry and other marine organisms. The Rotifer itself has little nutritional value, but it can serve as a food delivery system for the needed nutrients provided through the food (usually micro algae) that fills their bodies.

# Mbuna - (Pronounced um-BOO-nuh) African word for "rockfish." Rock-dwelling cichlids from Lake Malawi, Africa.

# Median Fins - Fins that are unpaired.

# Metal Halide Lights - Very brilliant and broad-spectrum lights used in some Planted Tanks for growing plant species that demand high-intensity light to thrive, and in saltwater Reef Aquariums.

# Milt - Fish semen.

# Mouthbrooder - Fish which protect their eggs and/or young by holding them in the mouth. Some may also clean their young in a similar fashion.

# Mulm - Solid waste materials such as plant parts, fish excrement and leftover food in various stages of decomposition. Aquatic 'compost' which benefits plants, but in an unplanted, poorly maintained system may result in a buildup of humic acids which will decrease pH over time leading to Old Tank Syndrome.

# NO - Normal Output Fluorescent lighting.

# Nano Reef - A small Reef Aquarium.

# Nitrate - The nitrogen compound at the third stage of the Nitrogen Cycle. Nitrate can be used by plants, further processed into nitrogen gas through Anoxic bacterial processes, or reduced by regular partial Water Changes.

# Nitrite - Intermediate nitrogen compound in the biological conversion of Ammonia to Nitrate in the Nitrogen Cycle. Nitrite is toxic to fish, but less so than Ammonia.

# Nitrogen Cycle - The natural process (nitrification) by which bacteria convert fish waste and other decaying matter into less harmful compounds. See article.

# New Tank Syndrome - Condition in which toxic fish waste products exist in the aquatic system because the Nitrogen Cycle has not yet been established.

# Nocturnal - Active at night.
