Why is there foamy white substance in your betta fish tank?
1 - The water has excess amounts of waste. The bigger the fish the more waste is created. Do a partial water change no larger than 30%. If you still see foam, wait another day or so for the parameters to level out, and then perform another partial water change.
Fluctuations in water parameters stress fish and lead to death. This is why you shouldn't change more than 30% of the water in one hit. Water changes of 50% should only be used in emergencies (pH crash, ammonia spikes etc)
2 - Excess amounts of water de-chlorinator or conditioner. Partial change of 30% should do the trick - ensuring you follow instructions on the de-chlorinator bottle. If problem still persists, change brands or look into Reverse Osmosis/Deionised water.
Yes and no. typically plankton applies to microorganisms that are not fish. They are small microscopic animals. But more properly, plankton means drifter or floater. Anything that floats can be called a plankton. For example, the Porteguese Man of War is a plankton, while a copepod and diatom is also an aexample of plankton. Some plant are considered to be plankton and some algae are forms of phytoplankton.
Can fish bite you after you catch them?
Yes, because as long as they are still alive and 'kicking', they can pin your with their barbs (Catfish) or you could poke your hand on their dorsal fins (bass, rock bass), and they can bite down if their jaw is free, but with a thumb in their mouths, they can't produce enough force upward to bite you.
(Try it with yourself and push down as hard as you can on your bottom row of teeth, is it easy to bite your fingers?)
Blob fish survive by laying on the bottom of the ocean floor and eat anything that floats by!
A fish cannot survive if taken out of water?
Fish do not breath air, they do not have lungs like humans or most other land animals.
They use gills to take oxygen from water.
If you take a fish out of the water it will suffocate and die from oxygen starvation.

There have been many theories as to the exact elements of the complex relationship between anemonefish and anemones. (I say anemonefish because a clownfish is really a clown anemonefish) Anemonefish live in the tentacles of the anemones and the tentacles protect them. They are also extremely territorial, and will defend the anemone at all costs. They also keep it clean and provide it food. The reason as to why anemonefish are never stung is still at large, although there are many theories about it. Some scientists say that the fish is covered in mucus, some say they build up an immunity, some say that the anemone recognizes it, etc. But either way, the relationship is called a mutualistic one, because both animals benefit.
What lure do you use to catch salmon?
Medium sized spoons (Little cleo is a good one) or minnow imitations.
How can a fish live in water completely covered with ice?

How do stone fish hunt other fish?
Stonefish are ambush predators. they camouflage on the substrate in their environment and wait for a smaller fish to swim over them. they drop open their lower jaw, creating a vaccuum which will suck in the prey item to swallow them whole.
Blobfish have no teeth. They eat, it is believed, by eat in tiny particles that drift by on the ocean floor, but no one is entirely how
Fish generally eat anything small enough to fit in thier mouths. Some fish are better parents than others, however. I've found having enough cover, plants etc, gives me more than desired survival rates for guppy fry. Making sure the adults are well fed helps too.
