Fin rot is the phenomenon where the fins of a fish gradually decay and are eventually destroyed. Typically, fin rot is either a symptom of a disease, oftentimes a bacterial or fungal infection, but it can also sometimes be a disease by itself. Fin rot is most often observed in aquaria and aquaculture, but can also occur in natural populations. [1]
Fin Rot is developed from bacteria eating or deteriorating the fins. The disease originates from "poor water quality, overcrowding, sudden temperature changes, fin nipping, or aggressive fish"; this leads to torn and shredded fins that could deteriorate the body tissue and prevent the regrowth of their fins.
Fin rot: Bacterial or Fungal: All: Erosion at edges of fins: Improve water quality. Aquarium salt baths can treat mild cases. Use anti-fungal meds if visible film/spores/tufts. Use gram-negative antibiotics otherwise. Columnaris: Flexibacter bacteria: All: Cottony growth near mouth and or patches of grayish-white film on the body or fins ...
The primary causative agents of fin rot are gram-negative bacteria such as Pseudomonas fluorescens and Aeromonas hydrophila. [71] Poor water quality, overcrowding, and stress are significant contributors to the onset and progression of the disease, as they create an environment conducive for bacterial growth and can compromise the fish's immune ...
The four most common illnesses are white spot, velvet, fin rot, and dropsy; with the exception of the latter, which is incurable, these ailments can be treated with a combination of over-the-counter fish medication, increased water temperature, and/or regular water changes. [41]
The wild-caught forms of the species are typically darkly coloured with yellow-ringed spots or ocelli on the caudal peduncle and on the dorsal fin. [6] These ocelli have been suggested to function to limit fin-nipping by piranha (Serrasalmus spp.), which co-occur with A. ocellatus in its natural environment.
Polypterus senegalus, commonly known as the Senegal bichir, gray bichir or Cuvier's bichir, is an African species of ray-finned fish in the bichir family, Polypteridae.It is a typical example of polypterid fishes, as most of its defining physical features are common across the genus, such as its ancient, lungfish- or arowana-like appearance, the ability to breathe atmospheric oxygen, and its ...
The adipose fin is a soft, fleshy fin found on the back behind the dorsal fin and just forward of the caudal fin. It is absent in many fish families, but found in nine of the 31 euteleostean orders ( Percopsiformes , Myctophiformes , Aulopiformes , Stomiiformes , Salmoniformes , Osmeriformes , Characiformes , Siluriformes and Argentiniformes ...
