Shouldn't I have to worry about any butterfly? The Klein butterfly you recommended, do you have personal experience with it?
As for nem. What should I look at instead? I could do frogspawn instead to mimic it I think.people do?
I'm going to work on tank later, plasti-dipping my mustangs wheels now, it's not cold and overcast so couldn't ask for better time lol.
Plus it's letting more bacteria to establish.
For my stock I'm thinking
2 clowns
1 helfrichi dart
2 diff blenny's but more of the peaceful.
1 fairy wrasse, would love a six line but I don't want to deal with their aggression
Butterflyfish
Lots of experience with Klein's in about a dozen or more systems. :thumb: All of the "reef safe" Butterflyfish come with the same set of caveats, more or less. Polyps are a part of their diet in the wild. (Why you see them recommended for Aiptasia and Mojano control...at which they excel when properly motivated.) For Klein's in particular, it's leather polyps..especially Sarcophyton...at least according to the books. In a home setting where they don't have to fend for themselves, polyps no longer seem to be a favored meal. That's not to say they will never nip a coral - they are what they are - but experience says they are a reasonable risk if you're aware of what they are.
I do think the Klein's is the safest of the "reef safe" Butterflyfish, and as mentioned it also happens to be much more hardy and a better schooler than all the more common Butterflyfish. Bonuses!
Anemone
Really depends on what your goal is. FWIW, your clowns don't "need" an anemone....unless you want them to need it. And even then I've known it to take 8 months or longer in extreme cases for clowns to "settle" into a resident anemone. If the goal was just to make the clowns happy, you'll do all they need by having a healthy tank with some rocks and sand.
If you were going to have coral, there's a good chance that anything with a wavy quality (polyps, tentacles...) will be a candidate for the clowns to settle. I've seen them settle in all kinds of Euphyllia (Torch, Frogspawn, etc), Whisker coral, on a big Montipora plate, Star Polyps, green and peach Briarium...even a cluster of rocks will work, though. Had some black clowns in a tank full of RBTA's that wouldn't go near any of the Anemone, but would spawn regularly on the back side of one of the rocks in the tank and defended that spot vigorously.
Beyond the rocks and sand, as far as the clowns will be concerned the rest is really "for you" and what you have planned for the tank.

If you really want to go anemone (I generally recommend against - especially if you're going to have $150 fish in the tank.) I would suggest a sand-anemone like a Purple (or less expensive variety) Long Tentacle.
Fish
I'm a huge fan of Barnacle Blennies (see a typical pic of one of my three in
Post #7 here.) They will appreciate a cooler tank (around 79 vs around 82ºF) if you can swing it, but are generally hearty even at tropical temps and are fearless little fish! They only get about 1"+ so they don't bother anyone. I've seen them co-habitate with Helfrichi's in a 20 gal without a problem. Blennies in general however, I would never classify as "peaceful". There are a few like the Midas and the small ones like the Barnacles (some other less common ones too) which always seem to have nice personalities....but the Bicolors, red-lips, lawnmowers, etc are all fairly large, boistrous (if not downright nasty...looking at
you Mr. Red-lip!! Been bitten by more than one!) fish for a small tank. Not necessarily bad citizens one and all....but again, not peaceful in my book. This quality makes them good tankmates for more fish-heavy tanks where you might need a fish that's not nasty, but can hold its own without a problem. The Tailspot Blenny would probably be another on the more-peaceful side of the family.
Fairy wrasses are cool - very peaceful. Depending on the nature of your clowns (some are more or less territorial) fairy wrasse like the McCosker's might become a target. (The more settled your clowns are to one spot, the less likely this will be.) Got your eye on any in particular?
