What could it be!

So first I bought this starfish (of course) when I got him he was only 1/2 inch haha I know of course only I would buy something like that but it was only 5 bucks haha and it was a STARFISH. Anyways I figured it died I never saw it again and its been 2 months. But I re did my aqua scape (pics later) and I found it lol. I have no idea what kind it is but it almost doubled in size since I got him.
Sorry it won't let me upload the photo hopfeully this link will work.

2nd I got a nem yesterday from the bio lab at the University, I was told it was a BTA but then I was told it was a ritteri nem, now I don't know, I don't know my nems to well. Its already attached and opening up my clowns love it and its doing well, but if its a ritteri..... yea. idk if I want it in my tank. The second pic of it is after I had moved stuff around so its kinda closed up.

 

Sorry about the weird photo, He opened up a bit more anyone have any ideas?

 

looks like a green bta to me lol they always lose there bubbles which suck but if i where u i would keep it. as for the "seastar" i have no idea just hope that its reef safe im sure someone will know

 

I thought it looked like a BTA too! but I googled ritteri nems and some kinda looked like it too... So I got confused. And the star has been in there for 2 months haha no harm done, he's only an inch now IF that, its the cutest thing Iv'e ever seen I tried uploading a picture I took with a ditigal SLR but it would'nt upload it was a really good clear pic too :/

 

how are you uploading pics?

and ur fb tread doesnt work fyi i think it hilariuos that you put you pics on fb lol

 

Lol well I had to put it somewhere to link it!? Im just uploading them from my computer.. like I did with the other pics from my phone, but it won't work on the ones I took from the camera, and they are just JPG's.

 

i always put mine on photobucket then move them over from there i think its alot eaiser

 

Hm. I could try that.. I don't think it will make any difference though.

 

its worth a try idk why its not working

 

I dunno either :/ Its okay I will figure it out another day I have class early tomorrow! I really do hope thats a BTA and doesn't eat my fish... lol im kinda worried its my first nem. But who can pass up free...?
