Rummy nose tetra dull pink nose

Hello fish folks

For those who had experience with rummy nose tetras, how long it takes them to fully adapted to a new tank or get their full coloration? I got 5 brilliant rummy nose tetras for a 20 gallon 3 weeks ago but they still don't have that redness they had at the store although brilliant rummy nose tetras aren't as red as some other rummy nose tetra species. Water parameters are not a problem. Tank fully cycled. When I introduced them to the tank on the first day, their noses had no color. No sign of stress after a few days. Eating well and behaving active in school. Google says it may take a couple of weeks to get their full coloration back but I have seen some rummy nose tetras have their full coloration on the next day after being introduced to new environment. They seem healthy although the tank is not too long for them to swim. I wonder if anyone had same problems before? Any thoughts would be appreciated.
(I'm also considering returning them for ember tetras or apistogramma)

 

Im not sure, they should be colored up by now, especially in that tinted water. What are you feeding? It could also be that their school is a bit smaller than it should be. A minimum of 6 is usually fine, but their true coloration usually only comes out with 8 or more fish.

 

What is your tank size, mates & acclimation process?

That could be one of the reasons. Thank you. I will see what to do next. I'm feeding them "High quality" flake food( The best I could get at the store although it's pretty cheap)

 

Your tank is a suitable environment for them, they are just very sensitive fish. It takes awhile for them to acclimate and be comfortable. I've had pencilfish in my blackwater for over a month now and still waiting for them to color up fully

20 gallon. No tank mates for now. On the first day I float the bad for 10 minutes then I release them to the tank right away since there is a dead one in the bag due to transportation. On the first day they were pretty stressed out, luckily no illness was spotted. First 2 days they were pretty much stay in the corner. After a week they were confident to swim however they like in a school and not fearing my presence

It's you again! Thank you for replying! If this is the case then it's gonna be a great experience waiting for them to color up. I'm going to enjoy the process of this. However, I don't understand how some people can have their fish to color up so good right after they were put in the tank.

Forgot to mention. PH is on the higher side. 7.1 and it used to be 7.4. Now it's stable at 7.1-7.2.

 

Do they look settled, not skittish at all? As above, a few more of them might help along with a more varied diet. For example good quality micro pellets and frozen foods like brine shrimp.

They are not skittish at all when I’m approaching them and they like to investigate when I put my finger on the glass of water surface. I will provide them a better diet and get 2 or 3 more. Btw these are brilliant rummy nose tetras with metallic scales. I wonder if I can get some regular rummy nose tetras to school with them?

 

I’m not familiar with the different types. If they are the same species but just different colour variants they will school together just the same.

 

I had 8 in my tank then added 12 more and it took 4 of the new ones like 2 weeks to get there full color.

Great thanks!

 

I know with rummynose the red "nose" is a good way to indicate water quality. If their nose is not bright red the water could be off somewhere.

 

That is a high 20, they would be better off in a long 20, as they do like to swim about. I don't see any mention of water temperature, they do like warm waters.

In the wild, different species of Rummynose are occasionally seen shoaling together during dry season. They should get by in your tank.
