Nematanthus gregarius, also called the clog plant [2] or goldfish plant, [3] is a species of flowering plant from Brazil in the gesneriad family, Gesneriaceae, making it a relative of such genera as Streptocarpus (African violets) and Aeschynanthus (lipstick plants).
The plant has a trailing, branching, and spreading habit; it is generally an epiphyte in nature and a hanging-basket plant in cultivation. The flower has fused petals. In some species, the flower has a "pouch" at the bottom. The fancied resemblance of such flowers to a goldfish gives these plants the common name goldfish plant or guppy plant.
Columnea gloriosa is commonly known as the goldfish plant (a name it shares with a number of other species), because of the fish shaped flowers it produces. Native to the Caribbean, Central and South American tropics, it falls into the genus Columnea. [1] Also known as a cousin to African violets. This plant is in the family Gesneriaceae.
The poison did not kill the fish outright, but merely made them torpid enough to be caught easily. [17] [18] Olax in the family Olacaceae is a climber with compound, dark-green leaves and white bark. This is the most extensively used fish poison among the Gondi of India. Typically in summer, the leaves of this plant are dried and powdered.
A planted reef aquarium filled with Bladed sand moss (Caulerpa prolifera) A seagrass aquarium housing several seagrass meadow inhabitants. Aquatic plants are used to give the aquarium a natural appearance, oxygenate the water, and provide habitat for fish, especially fry (babies) and for invertebrates.
Adult grass carps feed primarily on aquatic plants, both higher aquatic plants and submerged terrestrial vegetation, but may also eat detritus, insects and other invertebrates. [ 2 ] [ 5 ] They eat up to three times their own body weight daily, and thrive in small lakes and backwaters that provide an abundant supply of vegetation.
Corbicula have had global success as an aquatic invasive species, having been introduced to a novel range including South America, [5] North America and Europe.Human industrial activity, such as transport of larvae via ballast water in container ships, has been noted in the literature as a chief invasion vector.

Ichthyoplankton (from Greek: ἰχθύς, ikhthus, "fish"; and πλαγκτός, planktos, "drifter" [1]) are the eggs and larvae of fish. They are mostly found in the sunlit zone of the water column, less than 200 metres deep, which is sometimes called the epipelagic or photic zone.
