Softy question from a newbie

[tattooed reefer]

Why does part of my frag look bad / dead but the others are growing and moving onto live rock in first pic ? It's Been like this for about a week . The rest of my corals are looking great and been in tank for about 3 weeks . Thanks

It’s hard to say from just the pictures. Let’s start off with an overview of your set up and your parameters.

Start with tank size, salinity, temp, etc.

How long has your tank been running?

Do you have any test kits, what are you testing and what are the results?

Are you dosing anything into the tank?

What are you using for lighting/filtration?

We should be able to help once we understand some background on your system

28 gallon bow front , 1.024, 78 degrees , been up and running about four months used live sand and live rock . Cascade canister filter I clean every other week and I do 4 gallon water changes the other weeks, use reef crystal salt and well water . Current usa loop ic and orbit 24" light strip one of each and loop wave makers . Haven't tested the water in months since everything is on a schedule and doing well other then parts of the one frag . I know I know but I like living on the edge lol 4 fish since the first week, lawn mower blenny, neon Dotty back , coral beauty, clown fish and around 15 snails and hermit crabs .
