double posting here: 40G stocking ?S

So Im thinking about getting some fish and... lol Heres the possibilities, looking for advice, input, ect.

-Im wondering about a bicolor angel, will it work in my tank? I was reading about them and saw a couple places that said they are not very hardy, whats yalls experience with em? How badly do the nip corals/aggressivness/ect?

the other option on angel fish Im looking at are coral beauty or a flame angel.

-Also looking at a Klein's butterfly fish (Chaetodon kleini) it looks like it would probably eat my leather coral from what Im reading on it. How serious of a threat is that?

-The other fish Im looking at adding are a green clown goby, and possibly a royal garrama. If I did those two and one of the dwarf angels, would that work out well?

-Other other possibility, is I set up a sceeen top on the tank and get a snowflake moray (removing or sacrificing the emerald crab and maybe the hermits) add the coral beauty and give away the cardinals.


I have a 40g breeder, currently filtered with an undergravel powered by 2 powerheads (an aquaclear 50 and a petco brand meant for I believe a 50g) with ~3-3 1/2 inches of crushed coral and some live sand mixed in on the area not covering the under gravel filter. I also have a HOT magnum 250 canister on the back. I have ~30 lbs of live rock. Its been set up for about 6-12 months (kinda lost track since I was getting married/getting settled into an apartment in that time frame)

Its currently stocked with:

-2 pajama cardinals (which I might decide to take out at some point so if you want em...)
-1 neon goby
-1 claki clown fish and bubble anemone pair
-1 group of xinia
-1 finger leather coral
-1 mini carpet anemone
-1 pencil urchin (also possibly looking to take out of the tank)
-1 blue legged hermit crab
-1 red legged hermit crab
-1 emerald crab

 

I like Clown Gobies but even in tanks of 40 gallons you just never see them, they perch a lot and hide. I once went like 3 months without seeing mine.

Royal Grammas are great fish.

As far as Angels go I have had model citizen Angels go bad over night and start eating corals after having them for a couple years. I have had them become aggressive. I have also had a couple behavior perfectly so it's any ones guess. Personally Potters Angels have always been mellow for me but hard to acclimate. Make sure you get the appropriate food for the Angel or else you significantly shortens it's live span.

 

The potters angel is really pretty, but a little pricier than I can afford right now :'(

What food do yall recommend feeding a coral beauty or a bicolor angel? I've got the green algae sheets and a clip, and feeding my current inhabitants with a mix of frozen brine shrimp and frozen blood worms, instant ocean marine chips omnivore diet, and new life spectrum marine fish formula. Not sure if I want to add another flake or pellet food to the mix or maybe a frozen formula.

 

Get something for marine angels it should have sponge in it.
