Flowerhorn breeding resulted in culling of surplus and deformed fish, some of which were dumped in the wild in Malaysia and Singapore, where they survived and disrupted riverine and pond ecosystems. [ 3 ] [ 4 ] Like most other cichlids, flowerhorns are aggressive and can breed quickly, competing with and eating native fish.
Vernal pools, also called vernal ponds or ephemeral pools, are seasonal pools of water that provide habitat for distinctive plants and animals. They are considered to be a distinctive type of wetland usually devoid of fish, and thus allow the safe development of natal amphibian and insect species unable to withstand competition or predation by ...
Freshwater habitats can be classified by different factors, including temperature, light penetration, nutrients, and vegetation. There are three basic types of freshwater ecosystems: lentic (slow moving water, including pools , ponds , and lakess ), lotic (faster moving streams , for example creeks and rivers ) and wetlands ( semi-aquatic areas ...
For example, they recycle nutrients, purify water, attenuate floods, recharge ground water and provide habitats for wildlife. [16] The biota of an aquatic ecosystem contribute to its self-purification, most notably microorganisms, phytoplankton, higher plants, invertebrates, fish, bacteria, protists, aquatic fungi, and more.
This garden pond has two ponds separated by a waterfall with a one-foot drop; generally, the fish in the upper pond are smaller, and ones in the lower pond are larger.

Ponds, depending on their orientation and size, can spread their wetland habitats into the local riparian zones or watershed boundaries.
Habitat complexity provided by macrophytes tends to increase diversity and density of both fish and invertebrates. [49] The additional site-specific macrophytes' value provides wildlife habitat and makes treatment systems of wastewater aesthetically satisfactory.
