You just bought a 10g tank and put 2 green spotted puffers in it after 3 days your water in the tank is a little merkey what can you do to make sure the fish will live and make the water clear?

=== === This is just a suggestion but why not get a filter or get 2 smaller tanks, one for each of the puffers? What your experiencing is a bloom of oppertunistic bacteria which often occurs with new,un-cycled aquariums. I would recommend doing several large 50% water changes until it starts to look less cloudy but make sure to match the temperature of the tank water when doing so. You may also want to use a de-clouding agent which is available at most pet stores. You may want to invest in a stronger filtration system. Also it is a good idea to buy a bottle of "bacteria in a bottle' to help your tank cycle faster. Make sure to always use a water conditioner when you change water.

Why can't fish fly?

Fish lack the physical adaptations needed for flight, such as wings or strong enough muscles to sustain flight. Additionally, their bodies are optimized for swimming in water, which is more dense and requires different adaptations than air. Thus, fish are not capable of flying like birds or insects.

Why does a fish market at first seem to have a strong odor but in time becomes less offensive?

The response of receptor cells to odorants is, like other neuronal cells, variable depending on the conditions. There may not be enough of the odorant to stimulate an action potential; scavenger enzymes in the mucus layer may breakdown the odorant particles before they have a chance to bind to the receptor; or the receptor activation may cause an alternative signalling pathway to operate, preventing depolarisation. Even if a receptor does depolarise, it will eventually become adapted to the presence of the odorant and stop reacting to it. This is why, on encountering a strong smell that initially overwhelms you, after a few minutes you will fail to notice it any more. However, if you were to suddenly take a sharp intake of breath, you'd become aware of the smell again; the action of suddenly inhaling odorant-laden air exposes more of the olfactory epithelium to a greater amount of stimulus, which results in more action potentials.(smell@Everything2.com)

What can you do to provide more oxygen in the fish tank?
