Yes bc pretty much they stick to the glass but make sure to ask before u get a slatwater tank bc some fish might pick at it and make it die goodluck
Yes, if they want to.
if you can live with the smell
No cos gold fish are cold water fish and star fish are sea water

No it is totally not safe. DO NOT DO IT!
For a freshwater tank, its safe to add fish after the the ammonia, nitrite, and nitrate levels are safe for fish. Ammonia and nitrite should be at 0 ppm and nitrate levels should be very low, under 50 ppm. You should also make sure that other parameters are safe for the species of fish that will be living in the tank.
i hear it maked a great fish fellet
Yes
to be honest, its thick to put oxygen tabs in any tank. dont use them, your putting your fish at risk and its a waste of money. what fish do u have in the tank. then ill tell u if its safe.
No, dry clay is not safe to put in a fish tank because clay is made up of chemicals and when you put that substance of chemicals into water the chemicals diffuse (spread) and that could harm the fish. But if you don't have any fish in the tank its OK to put hard clay in it.
There really isn't much that you can do. The babies will have to fend for themselves. If you have plants and such in the tank they may be able to hide, but a few will be found by hungry adult fish.
An hour after the water is being cleaned by the filter than its safe to put them in.
