Hello, I have a 20-gallon tank, and I am a new owner. I am trying my best, but sadly, I have suffered a loss. I have lost 2 clownfish and one mandrian goby, thanks to Ichs, and I still have corals, Zoas, and a Candy Cane, but they don't look like they are thriving. In the tank, I also have one firefish and one perrpermet shrimp. But looking for some tips. Thanks In Advance!

How long has the tank been up? Did the tank completely cycle? Mandrians eat thousands of pods a day and need a well established tank. You can’t get that amount in a 20g tank unless you dose them every day. As much as I love those fish I wouldn’t attempt one in my 32g. It’s common to loose fish in the beginning, don’t beat yourself up.

The tank has been up for about 3 months and took 3 weeks to cycle, but I got my two clownfish right after, and for 2 months, they seemed to do well; they were eating well. When I got my mangernian goby, my fish store said they were fine for a 20-gallon tank. Last night, I got some calcium, alkalinity, and magnesium test kits. I only test alkalinity it was 9.6. Do you have any tips for the coral that I have

 
Can you describe what makes you think they aren’t thriving? Do you have closer pictures of the corals?

Are you testing ammonia, nitrite, and nitrates?
 
One of the zoas is open and doing fine, but the other one is closed, and I thought I was water flow, but I have not fully opened yet. It's the same thing with my candy cane coral. I test for ammonia, but not for nitratesa

Fish stores don’t always give good advice and can be less concerned with their animals than making a sale. Last request, could you post your parameters?
 
I would leave it fishless for at least six weeks to allow all three stages of ich to die off. Unlike your experience, clowns are pretty hardy. I really like the personality and colors of my royal gramma. With good maintenance you could probably get away with one more small fish. I love my tailspot blenny, small fish with a small bio load and a huge personality. I would recommend a small hospital tank, a cheap starter tank from Walmart and get some copper treatment just in case.
