Yes they do. if they wouldn't than most on the the eggs would die because they need a warm and comfy place to stay at till the next fertilization. - Dr. Henderson
Well they don't feed them with milk or anything because they are not mammals. They could get food for them, like birds, though.
I guess you mean Puffer fish. If so, then the answer is definitely NO! IMO there is no fish that should be kept in a fish bowl.
Puffer fish do not have small mouths. In fact they have a decently large mouth, they need this to fit their large teeth, which they chew on live rock to keep filed down.
they hide in the anemone
Puffers are in the family tetraodontidae and are called such for their ability to draw in sea water into their stomachs when frightened and can triple in size. These fish's internal organs contain a tetrodotoxin, which is powerful enough to kill a human, depending on the specie of puffer. Not all puffers have spines. The porcupine puffer is the one with spines, which make the fish look like a big spikey ball when inflated. The porcupine puffer is not a true puffer, but is a diodon. This specie also has tetrodotoxin in the organs. In Japan this fish is called fugu and is eaten, thought to be a delicacy and very expensive. Only licensed highly trained sushi chefs are allowed to serve this fish. The puffer fish cannot excrete toxins, but their cousin, the toby, can.
Catfish are sexual. They guard the places where they lay their eggs, males chasing off potential predators. Fish that keep or guard their eggs often produce a smaller number of offspring. Refer to link before for more information.
Some of the most spherical fish you will find are puffer fish which are marine fish and can be really hard to keep. Plus, they only got spherical when they are angry or stressed. Another fish I know that you may like is the Silver Hatchet Fish. These are tropical, therefore easier to keep, but they are more a 2D circle shape instead of spherical. Hope this has helped.
It depends on what other fish you have in the tank. Some puffers are aggressive and will not tolerate other fish. Puffers can also be very destructive and like to bite off pieces of your coral or decorations. They have to trim their teeth that way. They do make wonderful pets mainly because they have little fear of humans and make eye contact that melts your heart. I would research the exact species of puffer you want. Learn as much as you can about it. If you have time and want to read a great book, get "The Conscientious Marine Aquarist".
To blow up to keep predators from eating it. It aslo has a gland that has poison if a fish eats it. Either way it is guarded by adaptions.
First of all, to catch Mullet, you have to catch 60 fish. Then catch the lone fish that swims across your screen, but keep it on your line. That should be the bait for the big puffer fish.
Pike are predators, and help keep numbers of prey species from overpopulating the environment.
This is a good question> As since these fish are rarely monitored there is little information about this breed of fish> Best Answer Google and keep looking till you find the answer. :) Sorry I am unsure about the answer >
Most fish are darker on the top and lighter on the bottom. it is to camouflage from both its predators above the water and predators below the fish.
