No, the minerals that help make up the starfish will contaminate the water and through off your chemical balance.
No, it would not survive.
No more than a dried out Egyptian Mummy can be brought back to life. No, once a starfish is dead and dried it remains dead.
I have freshwater fish and i use aquarium salt. I put more in every time i do a water change
Tropical usually refers to Freshwater tropicals; and so the answer is no, because all starfish are saltwater.
I would say yes it would be ok not to put anything at the bottom of the aquarium. Gravel, stone and plastics are usually used for appearance. If it is a freshwater aquarium and if you plan on using live plants then gravel is necessary.If it is a salt water aquarium then it is necessary to use live rock and live stone.
I think it doesn't depending on how much you put in the water. My class put goldfish in a cup with water and BTB. It had absolutely no effect on the fish.
Good choices would be a pea puffer, spotted puffer, or a figure 8 puffer
Decorations (bridges, houses, caves, etc.), plants (live or fake), or even mini statues that you are willing to sacrifice.
They're designed for salt water, not fresh water! Just the way they are made. You can get aquarium salt from your local pet store, but don't put any in there if you have other freshwater fish that don't need it. Or get a tropical freshwater fish like mollies instead!
why do people put starfish in the window
I have a 55 gallon tank with a large pleco, some mollies, a rainbow shark, a red fin shark, an albino clawed frog, a beta fish, and two dojo loaches. Can I put an eel in there? Like a zig zag?
you put the starfish on Poseidon's offering altar.
You can safely put 2ml into the 10l aquarium
