rocky shore anemones info needed

well there is a rocky beach near my house and i came across some sort of anemone. i never got them because i was scared that they were pest anemone like apitasia but recently i read they they are not pests and can be used for reducing nitrate phosphate in refugium and they dont spread. i would like to know that is it true? can i keep them in my tank? i dont have a sump. uploading some pics to show you how they look. pics are from internet. if these are good and not pests, ill get them and upload the pics here in this thread. in the pics they are green but here they are white in colour. they are Anthopleura sp.

 

At first I thought they looked like palythoas, but upon further research they definitely are not. Some of the Anthopleura sp. anemones are very colorful, that would be awesome to get some of those. But if they dont spread, how did they cover that rock? I would still be concerned with the potency of its sting.

 

iv seen fishes passing by. im confused. some are huge and some are tiny. i saw tanks full of these with diff. colours and with fishes. should i try with 1? im getting white 1z. i get my snails and blennies from the shore.

I would be more concerned with it stinging other corals than it stinging fish. One couldnt hurt. Id keep it isolated away from other corals though to start just to see how it does. Either way best of luck and post pictures of what it looks like!

 

i have softies. well il try putting it in a high light area in a glass cup first and see whether it stays there or no. will go in a day or two.

 

The cup idea is a good one. Good luck!

 

iv read that they prefer cooler temp. but here in summers the temp is 36C an winters 24C. they are there 365days year round.

 

Is that water temperature? I'm assuming not because that upper temperature is quite high for water. Water temperature is what's going to matter. Those look just like the ones in California, where the water is quite cold (usually around 13 C) even when it's hot outside. The link you provided is of a cold water tank.

This is one I took a pic of in California, the water was way too cold to swim that day.

 

well im talking about water temp. well summer air is 38C-40C and winter can go as low as 20C. well at home with fan i maintain at 29C and my reef tank i hav chiller so that is 26C in summer and winter without chiller its maintained at 22C
