I have 12 black neon tetras in my 70 litre tank along with ember tetras and celestial pearl danios, I would like to keep this tank just for the two types of very small fish, and move the tetras to my 125 litre tank, it would give them more swimming place.
In the 125 tank I have, 12 Green Neon Tetras, 12 Harlequin Rasboras, 10 glowlight Tetras, 6 Black Phantom Tetras, One Thicked Lipped Gourami, and 6 ottos.
Could I get away with adding the 12 Black Neons to the 125 aquarium?
 
Can you post a picture showing the entire 125 litre tank so we can see how the current fish look in it?

What are the tank dimensions (length x width x height) of the 125 litre tank?

How often do you do water changes and how much do you change?

How much do you feed the fish?
How often do you feed them?
What do you feed them?

What sort of filter is on the tank?
How often and how do you clean the filter?
 
Thanks Colin, I will stick a photo up shortly, tank dimensions it's a Juwel 125 litre, length 81 cm depth 36cm, hight 50cm.
I do a 25% waterchange weekly, I feed the fish a couple of small pinches once a day, and the Ottos two small cat fish tablets nightly. They get a good variety frozen daphnia, frozen bloodworm, good quality flake, bug bites, and probiotic tropical, and live daphnia, the frozen bloodworm and daphnia and live daphnia I only feed as as a treat once a week.
The filter is an external Fluval 207, I clean the filter once a month. I removed the juwel filter and box gives them extra room.
 
I'm guessing the 125 litre tank is already well stocked and doesn't have room for 12 more fish. If the aquarium was 4 foot long x 14 inches wide then it would be ok, but 81cm long is too short for 5 groups of tetras and rasboras, even if they are all peaceful. When you post the picture I will have more idea but I think my response will be too many fish.

You could do a bigger water change too if possible. Small water changes don't dilute nutrients as much as bigger chances. Assuming the tap water is good, doing a 50-75% water change and gravel cleaning the substrate each week would help the fish you have now, and if you did add more to the tanks it would be essential.

Filter cleaning once a month is great :)

I have no idea what probiotic tropical food is but it sounds like a gimmick. Considering where aquarium fish live, there is loads of bacteria in the water and adding more in their food might not be making any difference. Do you know what the ingredients are in the probiotic tropical food?

Fish meal, wheat, soya deducted, extracted toasted poultry meal, lucerne protein concentrate, lecithin, krill meal, monocalcium phosphate, yeast products stimmune, inulin, algae schizochytrium limacinum, and as many vitamins that I would be all day writing them down.

If 12 black neon is to many would I get away with splitting them, putting in 6.
If you think a 50% waterchange would be be better, I will start this Sunday, would that be weekly?

My lol at your comments was about the number of vitamins and taking all day to write them down. Sometimes the fish food companies add more stuff than most people take :)

I would drop this fish food. Apart from the vitamins most of it's rubbish and even the vitamins could be rubbish if they are for humans. And anything poultry is to be watched closely due to the drug resistant bacteria in commercial poultry abattoirs. It also has wheat as the second ingredient and that's just bad unless your making bread. The fish can't digest most of those ingredients.

Good fish foods shouldn't have any sort of grain in and certainly not near the start. Most will use a small amount of flour as a binding agent but it should be at the lower end of the list.

Avoid fish foods with any terrestrial plant or animal products in. Fish don't digest terrestrial plant or animal products well.

Try to get fish foods that contain whole fish and whole shrimp as the first ingredients, and then different types of algae. After that it doesn't matter too much what is in the food as long as it's not grains or land plants and animals.

You are better off keeping the 12 black neons together as one group.
 
The title of the thread is your answer. You didn't ask if this would work, or if this could be a good set up for the fish. You asked if you could get away with it. To me, that means you know you can't, but you're hoping there's an angle that you haven't thought of. There isn't.

You don't want to harm the fish, but you bought too many of them. It's get a bigger tank, or find someone with a larger tank and space to take the fish from you time...

There not to many, in my 70 litre tank, I just don't think they go with the very small tetras and danios, your right I probably shouldn't have bought them, but I did, they were the first fish I bought for this tank, I just thought I could squeeze them in the other tank, so I will just keep them where they are, I don't want a bigger tank, and I don't want anyone taking my fish.its probably the way I say things, maybe I should have said, do you think this will work,

Thanks for that, do you think a weekly 50% water change would be good, or maybe every fortnight?
 
These are beautiful shots of a beautiful set up.

I think we let what we are really slip by the words we choose. I think you chose your words well, as you weren't lying to yourself there. You were probably thinking it might be bad and something to get away with.

I'd still do weekly water changes, as much as you can easily manage. Even if you stay the course with the fish you bought, you still have solid stocking. I'd want to keep set ups that nice working smoothly.
 
I suppose it may be overstocked if I added the 12 black neon tetras, my main reason for thinking it would be okay was. My 125 tank is a juwel and I took away the black box and internal filter, replacing it with a fluval external, giving them more room, I still think it would be possible to split them, I know a shoal of 12 is better. But would a shoal of 6 not be okay, if not I will just leave them.
 
Separating into a smaller group after they've been in a big group may cause them to become more skittish. I'd leave them in the big group
 
Have you thought about swapping the black neons with the (smaller and less energetic) green neon tetra?
