Which fish should I remove

[OrionN]

I think my fish count is too high and need to remove some fish from my 320 gal tank. The following is my fish list:
Angels: Regal Angel 2.5 inches,
Watanabe Angel Pair essentially full grown 4 inches female 5 inches male(included streamers)
4 Flame Angels
Copperband Butterfly 2.5-3 inches.
Tangs: Purple 4.5 inches, Powder Blue 4.5 inches, Yellow 4 inches,Chevron 6 inches. Foxface 7 inches,
Harlequin Tusk 4.5 inches,
2 Marine Betta,
4 Clownfish (2 pairs),
1 male Lyetail anthias,
This is really strange because I started out with 5. The male actually the one that died, one right after the other. They paid too much attention to the females and not eat enough, got weaker and died. The next female turn male and same thing happened. He is last female to turn to male by himself. He is fat now that their is no female to harassed.
7 Royal Grammas.

I think I am removing one or some of my larger fish. Either one Tang, or/and the Wantanabe angel pair.

Which tang to remove? Maybe the Foxface. Utility wise, the Foxface is the best, but he does not look anywhere as nice as the rest of the tangs


Please give me advises, opinion, pro/cons. TIA

Which of the tangs has the worst attitude? I'd let that be your guide. Tough call for sure.

 

[CHSUB]

why do you think: "my fish count is too high"?

 

[brett559]

Anyone else think he's just bragging about his (amazing) stock list?

 

[brett559]

Kidding of course!

If you had to get rid of some - I'd ditch the yellow tang and foxface.

7 ROYAL GRAMMAS!

I'd ditch foxface and chevron. That is because I do not like foxfaces, and adult chevrons are rather drab IMO. That would free up a lot of real estate.

 

[nuxx]

Purple or PBT.

Asking for trouble one day IMO.

why do you think: "my fish count is too high"?

I change 50 gal weekly, feed them a lot, use Carbon and phosphate binder, have a great skimmer that I clean every week to keep in great shape. I have cyanobacteria on the surface of the sand and it is not going away with this maintenance regiment. This is why I think I have too many fish. I don't want to cut back on feeding significantly unless the fish count is significantly lower.

I need to break out my test kits (more like order some new test kits) and test for phosphate.
All the fishes are doing great. All fat, no fighting in the tank. I love all my fish, that is why it is so hard. I am leaning toward get the Chevron tang out of the tank since he will be a big fish. The fox face too.
I love the bright yellow of the yellow tang so I don't think I will get rid of him. Purple tang and PBT are so beautiful. I like to keep them too

The CBB really clean up all my worms on the surface of the sand, I think that is part of the problem. He just decimated all the worms on the sand. I moved him to the frag tank last weekend, and about to reseed the sand bed. I need to keep him around because he does keep all the aphasia at bay. He eliminated all the aphasia in my DT. I think I just put him into the DT whenever I start to see aptasia in the DT. The are in the plumping and sump rocks so I don't think I will ever get rid of all the aptasia.

I never have such problem Cyanobacteria like this before. Maybe something to turnover the sand would help.

I love all my little fishes. They add a lot to the tank. Large fish too but I do need to decrease the bio-load of the tank. Remove five little fishes is not going to have the impact of removing a large one.

Royal Gramma likes harem. You should try at least 3 in your tank. Singleton RG are sad IMO

 

[OrionN]

I think I will try to do my best, order test kits and see if I can get rid of the Cyano problem. If not the Foxface and the Chevron will have to go.

 

[CHSUB]

yes, test water first...is cyano your only problem? i've seen cyano problems with small bioloads. is your tank fish and amemone only?

 

[brett559]

Chemiclean. Worked for me like a charm. Used it - the cyano never came back.

 

[OrionN]

Brett,
I agree with you on which tang to remove, but not on Chemiclean.

I am not into chemical, especially antibiotic like Chemiclean. I tried my best to get rid of this Red slime, but both my phosphate and Nitrade is not detectable. I think I will change salt mix next and also get new membrane for my RO. I got about 14 ppm water come out of my RO, which is not the best.

Minh- my harem of grammas has gone from 6 to 4

Minh- my harem of grammas has gone from 6 to 4

What happened? Only time mine fight was when the male got old and weak. One of the female change to male and promptly killed him. He was not able to hide from the younger male in a 450 gal tank with a lot of rock and coral.
They are dimorphic. Male have more purple, less yellow and longer pelvic fins.

 

[pinnatus]

I don't know, for a while I could only find 5, now I can only find 4. I think they are killing each other off. I've had them since 1/30/15.

 

[OrionN]

They are in the rock. Do you know the well enough to individually ID them?

 

[pinnatus]

No but I think they are gone. I can only count 4 at any one time.

Honestly I'd get rid of the flame angels lol but I have particular hatred for them. I am a big believer in using natural methods, I work in a LFS and everyone just wants to pour something in there tank to fix things or to cycle the tank. But I personally gave chemiclean a try and it destroys cyano overnight and has never caused issues in my 100g SPS tank with anemones, 13 fish, and mostly sps but a few zoas and lps for coral. I'd buy the hanna ultra low range po4 checker and use it. If your po4 isn't that high I would use chemiclean and keep all your fish. If it is at high level then use more GFO or maybe introduce biopellets while running GFO to drop it more aggresively then decide if you want to remove some fish. Personally I'm super attached to my fish and don't want to let any go. I just had a big hair algae problem and I thought the same thing till I fixed my problem by removing it all and using a better GFO brand and I ended up fixing the HA and still got to keep all 13 of my fish in my 75g DT (albeit all fish are properly sized with the biggest one being a lineatus wrasse).

 

[CoralsAddiction]

I would remove Watanabei Angel pair and Foxface to start with.
