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]
Columnaris disease in young fish is acute and damages the gills, leading to death by respiratory distress. [1] In chronic cases, fin rot, or frayed and ragged fins, can appear. Lesions begin at the base of the dorsal fin on the back of a fish and spread over time, hence the name saddleback disease. Ulcerations on the skin, and subsequent ...

An effective way to clear Ich from a fish population is to transfer all of the fish carrying trophonts in their skin, fins or gills to a non-infected tank every 24 hours. Then the fish do not get re-infected and after a number of days (dependent on temperature) the fish have cleared the infection because trophonts exit within this period.
The torrentfish (Cheimarrichthys fosteri), or panoko , is an amphidromous freshwater ray-finned fish that is endemic to New Zealand. [2] Torrentfish are well adapted to life in shallow, fast-flowing riffles and rapids. They grow to a maximum of 20 cm (7.9 in) in total length, but more commonly reach 10–12 cm (3.9–4.7 in). [3]
Fingerling – refers to a fish that has reached the stage where the fins can be extended and protective scales have covered the body. [4] At this stage, the fish is typically about the size of a human finger, [5] hence the name. Once reaching this stage, the fish can be considered a juvenile, and is usually active enough to move around a large ...
