Strange Swimming: When fish are stressed, they often develop odd swimming patterns. If your fish is swimming frantically without going anywhere, crashing at the bottom of his tank, rubbing himself on gravel or rocks, or locking his fins at his side, he may be experiencing significant stress.
Ways to Reduce Fish Stress
Change water frequently to keep nitrate and ammonia levels low. Try adding water conditioners like API Stress Coat Aquarium Water Conditioner, which is formulated to reduce fish stress by 40% by removing dangerous toxins.
Stressed fish hide when they feel threatened. This might be because of aggressive tank mates, or it might be because they share a tank with another dominant member of their species. Watch for other fish chasing them when they come out of hiding and you might better understand the problem.
If fish are experiencing acute stress (i.e., gasping up at the surface, lying on the bottom and not moving, or darting around the aquarium), you can be pretty sure that the water has been poisoned in some way. … When fish show that much stress, get them into better water conditions immediately.
Some fish succumb to pH shock immediately. Others may exhibit symptoms including thrashing, darting, gasping, swimming near the water’s surface and trying to jump out of the tank. Such symptoms are the same as those that indicate toxins in the water — either cause is serious.
Yes they can. My chiclids often swim up and down when they see me because they know I’m their source of food. But they hide away when my brother or sister enter because seeing more than one person sometimes scares them. They also like to stare at me when I stare at them to look for infections or whatever.
Heat. While most quality aquarium heaters are good at disbursing heat in such a way that the water stays at a constant temperature, you may find fish hanging out on one side of the tank rather than another because they prefer the temperature.
If you did not use Tetra AquaSafe® to remove the chlorine, the fish gills are being burned. This will cause the fish to dart around the tank. … After 24 hours, the chlorine will evaporate out of the system, but the damage will already be done. This behavior can also be caused by fish fighting.
Let’s revisit the example of the fish playing dead. Some species play dead to fool other fish, often targeting scavengers as a food source. The Central American cichlid is a perfect example. … Fish swallowing too much air when swimming to the top for their food is a more common cause.
It’s pretty easy to tell when fish are sleeping: they lie motionless, often at the bottom or near the surface of the water. They are slow to respond to things going on around them, or may not respond at all (see some sleeping catfish here). If you watch their gills, you’ll notice they’re breathing very slowly.
For the most part, feeding your fish once or twice a day is sufficient. Some hobbyists even fast their fish one or two days a week to allow them to clear their digestive systems. Larger, more sedentary fish can go longer between meals than smaller, more active fish.
If the aquarium is too small, or bare of plants, rocks, substrate etc. and it has no outlet for natural behaviours, then yes – they will get bored. We often get fish from people who keep them in tanks that are dull and too small.
Yes and no, according to fishing pro Tom Redington. Since sound doesn’t travel well between air and water, loud talking or screaming will be barely noticeable to the fish underwater. They won’t get spooked or scared. However, sound that occurs underwater is loud and travels fast.
They do not. I sincerely doubt it, some fish are quite smart but generally speaking they’re not nearly intelligent enough to even understand the concept of what a “name” is.
Fish are attracted to certain sounds and vibrations and not to others. Certain types of music and sounds repel fish while others interest them. Music and other sounds can define the change in the way fish behave in the water, including their eating and swimming patterns.
Unlike plants, fish do not have a biological need for light, so they require less. Natural sunlight at noon has a rating of 5500 Kelvin. How long should I keep my aquarium lights on? To provide animals and plants the lighting they need, 10 to 12 hours a day is sufficient.
Biologists have documented fish playing with a bottom-weighted thermometer and other objects. Play, like much of animals’ psychology including emotions, motivations, perceptions and intellect, is part of their evolutionary history and not just random, meaningless behavior.
As fish grow larger, make sure that they are not at risk of getting stuck in any of the toys, decorations or devices. … However, like most creatures, fish need stimulation to be happy and healthy. Buy toys for aquarium fish to give your pets opportunities to exercise and play.
