I've attached a picture of my hammer and frogspawn corals. Could anyone explain what this is and what causes it? I'd assume it's my fault because the tank is relatively new. Both of the Euphyllia corals look like this :(

It could be the tank is still too new, yes. If you can your dull water parameters and other details that would help.
Sure !
Salinity : 1.025
Ammonia : 0
Nitrite : 0.25 (just had a snail die while I was away for a couple days)
Nitrate : 9
PH : 8.2 - 8.4
I don't have test kits for the other parameters yet , but my LFS tested my water the other day and told me it was fine .

Nitrite is something I (and many others) don't even test for anymore, just FYI. I would look at testing for phosphates on your own, and get the alkalinity, calcium and magnesium periodically tested.

Euphyllia can sometimes be finicky if you don't have just the right lighting, flow or water parameters. I've got a hammer that's slowly recovering right now - and it got ticked because a torch stung it. It's taken over a week to try and fine a spot where it's slowly recovering.

How do I know what the best lighting and flow are for the corals ? is there a way for me to visibly look at them and tell?

Flow is easier to check than lighting. If they're blowing over like they're in a hurricane, it's too high. To tell if you have the right level a PAR meter is your best bet.

Ok. I moved them both into a smaller tank I have that's about 6 months old now . They seem to be doing better. The frogspawn has it's color back and the hammer has like two little spots of color. How do I know they're fully dead ?

All the tissue will leave the skeleton and the skeleton will be the only thing left.

Oh okay. I think I'll be able to revive them then. Both of them still slowly open up still. The hammer looks so bad. The frogspawn has gained most of it's coloring back compared to the initial picture I posted .

That flesh is recently gone, you can see the skeleton is pure white.
Your tank is not ready yet. Keep them in that smaller tank (or the oldest tank) and keep the water as stable as you can. Hopefully they pull thru.

This is what it looks like as of today . Would you say it's improving ?

I have a toadstool lol why
Get rid of it. Hard corals don't like leathers. I ditched a kenya tree the wife loved so my torches would inflate more. Made a great difference. Toadstools are worse. Maybe lots of csrbon.

The OP's first picture shows mesenterial filaments out and it's mouth wide open. so its either ticked off, or possibly splitting. The only time I've seen my frogspawn put out its mesenterial filaments was when it was in the process of splitting.

How long has this coral been in the tank?

I also noticed in the pictures that the coral is in different spots, looks like it has been moved. Which is another thing than can/may tick off a coral. find a spot for it and then leave it alone and let it get acclimated to its new spot.

The follow up pictures look a lot better... no more mesenterial filaments showing and a little more polyp extension.

hopefully it was just getting adjusted.

Leathers give out toxic chemicals that can kill other corals. I had a killer Nepthea that killed all of my hammers. They looked exactly like yours does: all shriveled with the filaments out and the flesh gone. I removed it from my tank and haven't had any issues since.

I'm not saying to toss the toadstool just yet, but it's something to keep in mind.

the first picture is about a week and a half in the tank. That tank is about a month old so it's relatively new. The second picture is in my 5 gallon tank that's about 8 months old. I moved it in an act of desperation to save it lol. It's like 4 days later and my hammer and frogspawn are doing better. The hammer almost lost all of the color in it's tips but it's slowly coming back. Just did a dip in Lugol's solution bc someone suggested I do that to help healing.
