Frogspawn/Zoa placement and hitch hickerclams

[BeachVacationer]

Today I bought 2 frogspawns, a xenia, and a GSP frag to go along with my zoas in my pico 5 gallon tank. I put my zoas right in the middle and the new frogspawns on either side. Is this too close? Will the frogspawns kill the zoas in that location you think?



Also, I removed my zoa frag from the ceramic plug and noticed 2 clams on the underside of the frag. I removed them and just put them on my sand substrate. Didn't know if they were alive or not. The smaller one disappeared so I assume it buried itself. The larger one is still there. This picture isn't the greatest, but the 3/8 inch clam is still there on the bottom left in this picture. Should I remove them from the tank? Is there harm to leave them in the tank?



As always, thanks for any input!

Definitely stick them in the sump or fuge until you get a good ID. The pictures are very small and are hard to see. There is a hitchiker sticky at the top of this page, folks are pretty cool about identifying the hitches.

Clams are filter feeders to help your water and nitrates. As for the Frogspawn, they will kill the Zoanthids and if you place your Xenia too close, eventually it will overgrow and kill your Zoas as well by taking up all the light and not allowing your Zoanthids to open up fully.

So if the sweeper tentacles of the frogspawn touches the zoas, that will kill them. Do these tentacles come out when it's completely dark? Also read to reduce flow to prevent them from getting long. I've yet to see these tentacles from either one.
