Clams

[Schwab94]

Ive got two little clams in my tank and over night one of the clams appears to have opened up so wide it split in two. My second clam looks just like it did yesterday but im now worried that he may be next for what effected the first. Had both clams for about 3 months now, they're my first clams in my first saltwater

In the tank are 2 clowns, 1 blue wrass idk the name specifically, 1 lawnmower blenny, 3 turbo snails, 3 hermits, 3 conch snails

They look on the smaller side, it it looks like it opened too much it’s probably kicked the bucket. Wave a hand over it to see if it smacks shut immediately. If not, it’s dead. Take it out before it pollutes your tank

On a side note that cleaner wrasse needs quite a lot of feedings by the way to be kept healthy / alive. Apparently 2 times+ a day is a must and plentiful fish for it to nibble on for snacks. I may be wrong but you might wanna do some research just in case.

Clams less than 2” have a poor survival rate.
Look quite small in the pic.

This and the tank is most likely too small to house a cleaner fish like that, It'll get quite big, and annoy all other fish - continiously pestering other fish to clean them.

I would remove the dying (dead) one immediately. Closely inspect it's foot for tiny (pyramid) snails. If you find even one, pull the other clam and remove any you find or it will quickly follow it's tankmate.

How old is your tank, what are the parameters, and what are you using for lights? Clams are one of the very most demanding of the creatures we keep - generally not the best choice for a new tank/new reefer because of their need for nearly perfect, stable water conditions.

The one on the left is dead. It will not recover. The one on the right looks okay for now. As stated above, take out and look for pyramid snails. They are most active after lights out at nighttime.
Sorry for your loss. These are finicky animals and not much we can do when they go down hill.
