    a circular polarizer will do some help..but note, it's only some help..

    you probably need a polarizer filter. But if low light situation, do take note that this will reduce the amount of light reaching the sensor so you prob need to up the ISO to compensate, esp for moving object like swimming fish. You could try varying your angle to avoid the reflections from ambient light too.

    Try not to use the flash as this is the main source of reflection. Some museums don't allow flash fotography so make sure you check first. If you really want to use flash then make sure you stand at an angle to the glass. Imagine standing in front of a mirror. You can see yourself in the mirror because the light is reflected back at you. If you stand at an angle to the mirror, you can't see yourself anymore... same idea with glass...

    ok, my opinions differ. i shoot arowanas a lot.

    cpl are of zero helps. esp if the glass is thick.

    at the meusuem, try shooting at a longer exposure and getting as close as possible to the exhibit, use a monopod for support. ok taken that that's often not very possible, then use a flash. flash can cause reflection, but u can diffuse or shoot it at an obsure angle. standing at an angle might help, but then it would take quite a bit of trial and error.

    with fishes, the opposite applies. u can't get close cause the fishes will be frighten, esp those in fish tanks. so i normally shoot at a distance of 1meters, tripoded and pendicular to the tank. this helps to cut down reflection, avoid shooting at angles. and make sure the tank is amply lit. top light above tank is best, or light from within tank. else u can use a flash with diffuser, bounce it off the celing. however, all this dun appy at public aquariums, with those just snap away. light is good and fishes are deaf to ppl.

    If this helps, try not to use speedlights but strobes if possible so that you can see where the reflections are and adjust your camera position (i.e @ an angle) to avoid the reflections.

    if you can, rest the lens against or very close to the glass... will minimize reflections...

    that will be good, but the fish will swim away.
    either that or the musesum curator will chase u away.

    Wouldn't shooting pendicular to the tank cause your own/your camera's reflection to show?

    nope. the catch is this, the light from the top or bottom of the tank must be strong.
    with most fishtanks, the light source is from the top, so no problem.
    and also to get the pendicular exact, else reflection would show.
