Livestock For 75 Gallon

Oh and with a butterfly, one source I read size is the key 3-5" being good since too young and they just don't handle the stress well and too old they are less likely able to adapt to different foods.

I just got a CBB that lucky for me took right to the food just a few hours after being in the tank.

 

I had a long nose in a 75 and it did pretty well. It was the only butterfly I had in the tank though.

 

I wouldn't look at butterflies any time soon. They can cause issues with corals and those that don't can be tough to keep (e.g.) copper band. Stick with hardier fish until the tank is well established.

A lot of good fish have been mentioned, I will add in a few and reiterate previous mentionees.

I love Royal Grammas. They are very colorful with some personality to match. They are hardy and a great addition to any aquarium.

Any number of tangs are great additions. My personal favorite for mid sized tanks is the purple. Very hardy and colorful. The kole and flame fin tomini are fun too.

Bi-color blennies are one of my favs too. Not out and about too much, but very cool to watch as they perch on and in live rock.

Flame hawk fish are awesome, but will eat smaller inverts.

Plane door closing more to add later.

 

I do have a flame angle - with no issues
But I would stay away from butterflies since there are many stories of them eating coral. Just remember it's very very tough to get a fish out once they are in.

I love my Gamma - great personalities
Also cardinals are cool

I would start with hardier fish - I didn't add my Flame till it was 5 months old
But you will love this hobby

 

More stuff as promised:

There are a number of reef-safe wrasses that are really cool and quite lively. Many are so colorful they look like they must be fake. Just keep a lid/cover/jump barrier on as they tend to jump.

I like Midas Blennies (though not as much as Bi-Color and I don't know why )

Others have mentioned Bangai Cardinals. Cool fish, don't keep more than two in a tank.

Keep room for the Flame Angel. They nip at SPS and some LPS so you have to keep them fed, but really I only worry about keeping SPS with them.

 

Ill definitively look into these fish, how many fish can I keep in this tank?

 

Thanks aha, yeah I love the cardinal I have now, will most likely be transferring him over to the new tank!

 

There are two factors that determine how many fish you can keep. One is the physical size and make up of the fish you put in. Too many fish can mean added stress and potential conflicts. The other is the size and efficiency of the "filtration." I put filtration in quotes because this primarily means the combination of live rock, live sand, protein skimmer and (for the quotes part) water changes. Other filtration can mean things like algae scrubbers, etc., but we'll leave those out for right now.

So with a decently stocked sand bed and good live rock combined with a properly sized, efficient protein skimmer I would go with something like:

- A medium sized tang like a purple or kole.

- A small reef-safe wrasse. There are a ton to choose from that look awesome. They also tend to be active swimmers so add some nice movement.

- A Royal Gramma because I just love them and they don't take up any real "swimming room."

- A couple Bangai Cardinals.

- A Bi-Color or Midas Blenny. I consider Blennies almost "free fish" as it relates to bio load. They have a small impact overall.

Once you have your tank set up for a little while and parameters are stable you could add a Flame Angel or other pygmy.

Now I would consider this a fairly heavily stocked tank for its size, but the mix of swimming and hiding fish means it can work with proper filtration.
