Fish coming to the surface indicates a lack of oxygen in the water in the fish tank which causes the fish to swim up to the surface to breathe, as the concentration of dissolved oxygen is highest here.

Increasing the water movement in your fish tank is the quickest way to increase oxygen (O2) levels in a fish tank, as it allows more O2 to dissolve and carbon dioxide (CO2) to be released.

This can be easily done using an air pump, performing large water changes, manually stirring the water, or placing a fan near the aquarium.

The best things to feed yellow fish are pellets, brine shrimp, Krill and mysis shrimp.

To enhance the yellow in fish you can add a food additive to your fishes food known as Carophyll yellow which is very effective at enhancing the color of pond fish and aquarium fish.

The food that brings out the blue in fish is seaweed.

The color of food you feed your fish does affect the fish and makes the fishes color look different.

Although you can't completely change the fishes color by feeding it certain foods as the color of fish are genetically set.

The best way to make your fish more blue is to use seaweed with their food.

Or feed the fish some seaweed along with their regular food which will help make your fish more blue.

The most common way that they dye fish is through dye injection through use of a syringe.

Fish are most often injected with the dye multiple times and the fish may also be dipped in caustic solution to strip the fishes outer slime coat and then dipped in dye.

Dye fish with this method is very likely to kill the fish as well, especially if not done correctly.

While dyes don't typically hurt fish or other aquatic animals, they can affect desirable submergent plants that fish and other aquatic life may use for food and habitat.

There are three common dye colors available for use: blue, black and a mix of the two imparting a deeper color to the water.

Scientists group fish into three main types.

They are divided into these groups because of the structure of their mouths and the types of skeletons they have.

There are jawless fishes, cartilaginous (cart uhl AJ uh nuhs) fishes, and bony fishes.

All three types are "cold-blooded," or ectotherms.

Fishes are a group of animals that are completely aquatic vertebrates that have gills, scales, swim bladders to float, most produce eggs, and are ectothermic.

Sharks, stingrays, skates, eels, puffers, seahorses, clownfish are all examples of fishes.

The biggest fish in the ocean is the Rhincodon typus or whale shark.

Despite their tremendous size and intimidating appearance, whale sharks are commonly docile and approachable.

Need some help, friends! After watching a documentary about tropical fish, I'm inspired to revamp my tank, starting with a honey gourami. I'm thinking of adding some companions. What would you suggest for a harmonious aquatic community?

Hey there! Totally get the excitement after watching something inspiring. I had a similar situation after a documentary binge! Honey gouramis are such peaceful and beautiful fish, a great choice to start with. When it comes to tank mates, think peaceful and non-aggressive. Small schooling fish like neon tetras or harlequin rasboras create a lively yet serene tank. Even some types of dwarf corydoras could be a good fit, adding activity at the bottom of your tank.

I remember when I first introduced a honey gourami into my tank; it was like watching a graceful ballet underwater. The harmony was incredible, especially after I carefully selected the right companions. You really want to ensure a balance in your tank that reflects their natural habitat.

There's actually a helpful guide I stumbled upon at https://www.allaquariumfish.com/selecting-honey-gourami-tank-mates-what-you-should-consider/ . It offers some great insights into selecting compatible tank mates for honey gouramis. Worth checking out for some extra tips!
