Yes, salinity does increase with temperature. This is because as the water gets warmer, more water evaporates from the surface of oceans and other bodies of water. As the amount of water decreases due to evaporation, the salt concentration increases in a process known as “salting out” which leads to an overall higher salinity level…

A cycled tank refers to an aquarium that has been set up for some time and is stable with the water parameters. An ammonia spike in a cycled tank can occur if there are too many fish or other organisms present, resulting in an excessive amount of waste being produced. Additionally, overfeeding, adding new fish…

Yes, semi-aquatic plants can be submerged. This type of plant is adapted to living in both aquatic and terrestrial environments, so it is well suited for being immersed in water. Semi-aquatic plants typically have thick stems or rhizomes that are able to store oxygen and provide buoyancy when submerged. They also often have leaves with…

Ich, also known as white spot disease or ichthyophthiriasis, is a common parasitic infection among aquarium fish. It can be highly contagious and if left untreated it can lead to the death of infected aquarium fish. The parasites that cause Ich are called Ichthyopthirius multifiliis (or Ick). These parasites attach themselves to the gills and…

My cichlid is turning white because it could be suffering from a disease called ‘Velvet’. Velvet is caused by a single-celled parasite that can attach itself to the fish’s scales and release toxins as they feed on the fish’s blood. It causes the scales to become discolored, which can range from yellowish-brown patches to an…

Yes, coralline algae is good. Coralline algae are red and purple encrusting algae that form a protective skeleton for many reef-building corals and other marine life. Coralline algae provide essential habitat structure on coral reefs by creating nooks and crannies to which fish, invertebrates, sessile organisms, sponges and other species can attach to. They also…

UV sterilizers are a popular choice for aquarium owners who want to keep their water clean and clear. They use ultraviolet (UV) light to kill bacteria, algae, and parasites that can pose a risk to fish health. Pros of using UV sterilizers include the fact that they work quickly and effectively at killing unwanted organisms…

If you have an overgrown pleco, there are several things you can do to manage it. First, try transferring the fish to a larger tank; plecos grow very quickly and need plenty of room to swim around. Additionally, make sure that your tank is well filtered; plecos produce large amounts of waste which must be…

For a 55 gallon tank, the recommended substrate amount is between 45 and 55 pounds. This will be enough to cover the bottom of the tank with a depth of 2 to 4 inches. The exact amount needed depends on your desired look and what type of substrate you are using (e.g., sand or gravel)….

It depends on the type of fish and its size. Generally, small fish can regrow their fins in a few days or weeks while larger species may take several months to many years. In some cases, the fin will not fully regenerate due to damage or disease and might require surgery for complete recovery. The…
