More fish?

[towels]

I have an IM 75 gal ext and would like to add another fish or small(ish) school but wanted to see the consensus

CURRENT STOCK
2 clowns
2 mandarin gobys
1 blue star leopard wrasse
1 black leopard wrassse
1 copperband butterfly
1 Helfrichi firefish
1 sunburst anthias
1 borbonius anthias
1 marine betta
1 gum drop goby

I feel like im maxxed when looking at the list but when looking at the tank I feel otherwise. My 2 anthias will occasionally chase the wrasses. Could potentially bringing in a larger fish help de-escalate the aggression or would that just increase it?

Wants and desires
- Tang (have steered away since I have the cbb and anthias)
- blue/green Chromis but I can’t get them from marine collectors/biota (don’t want to qt this time around)
- two spot blenny
- melanarus (steered away)
- rhomboid wrasse
- multi bar angel

I don't see why a small tang couldn't be added. I don't think there would be any agression toward CBB or anthias bristle tooth, scopas, yellow, purple.

i have a blue hippo, purple, sailfin and powder brown in a 75. all bought very small. but i knew i was upgrading in 6 months or less

i generally don't go for wrasse, everyone i have owned has managed to jump out.

what about a dwarf angel? can never go wrong in my book with a coral beauty

Hey towels, wassuppp? :)

Looking at your current list, I’d say your 75g is already on the high side in terms of long-term bioload and territorial dynamics — even if it “looks” like there’s room. With a CBB, anthias, and multiple active wrasses, you’ve already got a pretty busy mid-water column.

On the anthias/wrasse chasing:
Occasional chasing is normal, but adding a larger fish to “break it up” is risky. In many cases, it just reshuffles the hierarchy and creates new competition rather than calming things down.

On the fish you mentioned:

• Tang – I wouldn’t in this setup; space and activity level make it a poor fit long-term.
• Blue/Green Chromis – Fun movement, but small groups can whittle themselves down over time. If you can’t source healthy captive-bred from a trusted supplier, I’d skip for now.
• Two Spot Blenny – Safest choice from your list. Peaceful, full of personality, low bioload.
• Melanarus Wrasse – Hardy but could add to wrasse-on-wrasse tension and may harass mandarins.
• Rhomboid Wrasse – Beautiful and generally peaceful, but still a high-energy wrasse.
• Multi Bar Angel – Delicate to acclimate, potential coral nipper, and adds significantly to bioload.

Other ideas that could work well in your setup:

• Midas Blenny – Lots of personality, active swimmer without adding aggression.
• Yellow Watchman Goby + pistol shrimp – Great symbiotic behavior and keeps to the sand area.
• Royal Gramma – Peaceful, colorful, tends to keep to its cave.
• Orchid Dottyback (captive-bred) – Striking color, stays small, and CB individuals are generally peaceful.
• Tailspot Blenny – Similar benefits to Two Spot, but even smaller and very peaceful.

If it were my tank:
I’d skip the tang, avoid adding another high-energy wrasse, and go for one of the blennies or a small, peaceful goby/basslet species. This keeps your bioload in check and avoids upsetting the current social balance. If you want to reduce chasing, adding more rockwork and swim-throughs often works better than adding another “referee” fish.
Sometimes a tank “feeling empty” is actually the fish using the space naturally — which is exactly what you want for long-term harmony.

I’d hate to have to rehome a tang and I don’t think I’d be able to upgrade from the 75 for quite some time. I may go for a bristletooth or white tail since they’re a bit smaller. If I recall correctly I read that coral beauties can be a real hit or miss with aggression / coral nipping.

 

[PPBlimpy]

i have never had one nip at corals. Agressive a bit when they are not fed enough.

 

[BryanM]

If you have to have a tang I like the whitetail a lot... But I'd probably opt for the blenny option in your tank.

 

[towels]

Bump. Still considerin. I feel like I could def add one more active swimmer when looking at the tank

Biota yellow? Is that pushing? I don’t want to rehome any fish

post a pic of ur tank try to include all the fish in it and lets see what space is like

Going to say no on the yellow. That fish will get big for the stocking that you have. I'm going to tag @i cant think to give you some more suggestions!

Major questions before I really chime in…

1. Got an FTS (Full Tank Shot)? If so, that would help the most - not just from an activity/space perspective but also, certain fish require different rock scapes to be truly happy & thrive. Angels (Paracentropyge especially) love clinging to the rockwork and having caves/overhangs to swim around rather than active swim room.

2. Sand bed? I’d assume you do seeing your wrasse list but I also have coral trays with several sand sleeping wrasses in and there’s no sand in there.

3. Again, may sound odd but what are the tank dimensions? I work around dimensions rather than volume (for the same reason as the 1st question).

Thanks for the reply. Here are some shots. I added some really old photos to better showcase the scape.

I previously had a flame angel with the clowns and copper band, but he was an *** to the clowns so I removed him. Probably won’t shoot for another angel. However, I really do like the multi bar angel but that may be Sicily with the cbb.

Sand bed is 2-3 inches. I added more because I really like my leopard wrasses and I felt bad since they would sometimes struggle getting into 1-2 inches of sand.

IM Ext 75, 3x2x2. Will get a photo / vid with fish when I get back in town

I added a biota yellow tang to my 100 gal. tank last week. Tonight I noticed it actively trying to injure or worse my cbb. I added some mirrors and more food. The tang might have to be rehomed at this rate.
