Also known as the Lace Gourami, this cool tropical freshwater fish is one of the most popular Gourami fish for aquarium lovers, thanks to it’s beautiful appearance and its hardy build. They are easy to care for, and can be kept in tanks with at least 30 gallons of water, but like many other types of Gourami, they do require space at the top of the tank so they can breath air.

Histopathologic alterations of gill, liver, and spleen were studied in feral fish from three freshwater ecosystems that experience different types of contaminant stress. East Fork Poplar Creek (EFPC), a third-order stream in East Tennessee, receives point source discharges of mixed contaminants from a nuclear weapons facility located near its headwater. The Pigeon River (PR), a high-gradient fifth order stream, is impacted by bleached kraft mill effluent (BKME). Hartwell Reservoir (HR), a US Army Corp of Engineers impoundment of the Savannah River, contains high levels of PCBs in sediment and biota. Brushy Fork Creek (BFC), the Little River (LR), and the Tugaloo River (TR) are relatively free of contaminants, and served as reference sites for the three respective ecosystems of this study. Certain organ and tissue lesions, detected microscopically, were common to fish from both reference and contaminated sites. These included parasites, inflammation, glycogen deficiency, macrophage aggregates (MA), and diffuse fatty change in the liver; parasites and MA in the spleen; and parasites, secondary lamellar fusion, and variable epithelial cell hyperplasia in the gills. Lesions found only in fish from contaminated sites were: (1) cholangiomas in liver of redbreast sunfish (Lepomis auratus) collected from EFPC; (2) amphophilic and eosinophilic foci of cellular alteration, diffuse biliary preductular and ductular hyperplasia with islands of hyperplastic basophilic hepatocytes, and two metastatic thyroidal carcinomas in spleen of redbreast sunfish from PR; (3) severe lipidosis, vacuolated and basophilic foci in largemouth bass (Micropterus salmoides) from HR; (4) splenic lymphoid cell depletion and vascular congestion, with necrosis of reticuloendothelial cells in fish collected from EFPC and HR; (5) hyperplasia of mucous and chloride cells, deformed branchial cartilage, severe and diffuse aneurysms of lamellae, and edema at the base of the secondary lamellae were in gill of fish from all three sites. The finding of specific lesions only in fish from contaminated sites suggests a contaminant etiology. Histopathology biomarker lesions identified in this study are similar to those observed in laboratory exposures of fishes to specific pollutants. Further refinement of these biomarker approaches will be discussed in light of multiple stressors and their effects.

The majority of freshwater fish parasites hobbyists encounter are protozoans, single-celled, free-swimming organisms that frequently do not require a host to reproduce. Protozoans attach to the fish when they are overcrowded or stressed, causing extremely thinness, skin or gill irritation, difficulty breathing, agitation, appetite loss or even death. Protozoans are divided into ciliated and flagellated types, divided by the types of hair-like extensions that aid in their movement. The entire tank must be treated when protozoans are present; it's impossible to treat individual fish for this kind of parasite. Protozoans can be difficult to eliminate from a freshwater tank. The most common of these protozoans are Ichthyophthirius multifiliis, which cause the disease known as ichthyophthiriasis, also known as “ich” or “white spot disease.” Other common protozoans include tetrahymena, trichodina, Hexamita and Myxozoa.Whilst this list is just a small example of the types of fish you can keep at home in a beginner aquarium, we believe that these 13 are perfect for those with little experience, and each tick all the boxes we mentioned before, when looking for tropical freshwater fish.Trematodes are flatworms found either inside or outside a fish’s body. These flatworms, which attach to a fish's body, are also called “flukes.” Internal flukes are transferred by hosts other than fish, such as snails and related animals. Internal flukes eventually leave their host mollusks and then infest their permanent hosts: your freshwater aquarium fish. By contrast, external flukes are introduced to the host tanks by other fish, such as plecotomus, corydoras and some live-bearing fish, among others. Gill flukes and yellow grubs are two common types of trematodes. As the name implies, gill flukes attach to the fish’s gills, where they feed on the fish’s mucus, skin and blood. Gill flukes typically have the appearance of tiny, dark spots attached to the gill filaments. These fish can cause fish to become debilitated or even die. Yellow grubs are a large and noticeable trematode that attach to the outside of the fish. Although it does not appear to cause its host any distress, the yellow grub is aesthetically unpleasant.To maintain a happy, healthy, friendly community tank, it's important to ensure compatibility between the inhabitants. The freshwater fish compatibility chart below will give a good overview of the common types of fish that can usually be kept happily together. For first timers, or those who are new to the hobby and are setting up a community tank, this guide can help you make good fish choices. It will help you select fish that can live together in harmony, giving you a happy, healthy, friendly community.
