I am looking for some good corals that are cheap, easy to maintain and will live in various positions(top, side and bottom of the reef base)
My tank is 65 gallons has four percula clowns (two pairs) and live rock and 1 lobophyllia and 1 catphyllia coral. The water has a low to medium flow rate and I am planning on getting a yellow tang and some green chromis. (Maybe some other fish that will live with my setup)
names will do as I will research them further myself.

Will any of these fishes try eat a blood red fire shrimp, hermit crabs, star fish, or clams?

Magnificent Foxface
Copperband Butterflyfish
Raccoon Butterflyfish
Teardrop Butterflyfish
Falcula Butterflyfish
Golden Semilarvatus Butterflyfish
Blue/Green Reef Chromis
Ocellaris Clownfish
Green Mandarin Goby
Spotted Mandarin Goby
Yellow Tang
Blue Hippo Tang
Six Line Wrasse
Longfin Fairy Wrasse

I know the butterflys will try to eat the corals so doing a reef tank will be out of the question. Really want to do a reef tank but can’t have the butterfly eating at my money through corals. Also are all these fishes compatible with each other…I’m planning on having at least a 200 gallon setup.
Are there any corals that I may be able to have in the tank despite the butterflys?

I have a 72g with a 20 gallon sump setup as a saltwater coral reef tank. I grow plants above my sump and ended up knocking a small plant pot over and about 1/2 cup of Miracle grow fell into my sump. I tried to get as much out before it circulated through my tank but some still made it to the display. How is this stuff going to affect my tank?

The ingredients of the soil are as follows:
Total Nitrogen - 0.21%(0.12% ammoniacal nitrogen & 0.09% nitrate nitrogen) Available Phosphate - 0.07% Soluable Potash - 0.14%.

I tested my Nitrates Amonia and PH about 20 minutes after I cleaned it all out of the sump. Nitrate 20ppm, Ammonia 0, PH 8.2. Not sure if the 20ppm nitrate is from the soil or not as I have been putting off doing a water change for over 2 weeks. I have chaeto/macroalgae in the sump and it’s supposed to help remove the nitrates. Any help would be greatly appreciated. I am going to do a 20% water change tonight once I pick up some salt.

I have 2 small chromis, 2 small clowns, lawnmower blenny, cleaner shrimp, 2 peppermint shrimp, and a pistol shrimp that resides in the sump. 80lbs of sand, 75lbs of LR. All sand and rock was cured for at least 3 years before it made it to my tank. My tank is currently six months old. I have about 30 different corals, mostly softies and couple pieces of LPS and SPS. Please Help.
I have a bag of chemi pure (which is a high grad carbon) in my sump and its about a month old. Supposed to last 6 months. I will pick up a fresh bag to add to it.

I want to start a nano reef tank. Probably something in a 3Gallon tank that I can leave on my desk. A couple corals and maybe 1 or 2 tiny fish with some sand. But some things come into play as to whether or not I can start one.

1)I am complete NEWBY to saltwater setups. (I am willing to learn)
Can beginners maintain a nano reef tank? Are they more difficult to keep that bigger reef tanks?
2)I have a 150$ budget. That I cannot pass. Maybe I should buy a nano tank KIT.
Will i need expensive lighting(the light that comes with a kit is good enough?) and a water cooler for summer if I live in California?
3)I do not want to change the tank’s water every single week. (Every 2-3 weeks is fine)
Does a nano tank require more weekly maintenance than bigger tanks because of the smaller filter?

I know this is a lot to answer, but I would like to know these answers before I decide to spend my time doing research on saltwater setups.
I was thinking of getting something like this.

My somewhat new reef tank (about 2 months) is starting to get a slight cyanobacteria outbreak. While Ammonia, Nitrites are at 0 and Nitrates close to, I think this problem was due to using tap water in the initial setup and old PC bulbs.

I’ve replaced the bulbs and have done a number of water changes and the red slime algae seems to be lessening, I would like to get some snails to finish it off and to take care of some of the other algae in the tank.

I’m probably going to stay away from any hermits as I would like to build this into a reef tank and people have noted their hermit crabs messing with some of their corals. So for now I want to go with Astaea Turbos, but I don’t know how many I should get for a 55 gallon.
I’ve had snails in the past with no problems with them over-reproducing.

I’ve noticed a lot of the "janitor packages" included a sea star or two - would you recommend these? I’ve had a lot of problems in the past with algae in the sand. (Do the hermits do a good job of sifting?)
