Hiding Cardinal tetras.

[PKB]

Hi,

I have a heavily planted 2Ft tank and a month ago I add in about 10 pcs of Jumbo Cardinal Tetra (XXXL). But they have gone hiding and I can't get to see them at all.

I suspect that due to their small qty, they have no confident to swim out in the open. So I add in another 30 XXL Size Cardinal, it works for the first few days and now they have ALL gone hiding.

I try luring them out to the open by placing a tubiflex worm feeders on the front of the tank but failed.

Is there anyting I can do so that they can swim to the front of the tank?
There is no other fishes in the tank except a few ottos so they shouldn't be hiding any other agressive fishes.

I have to feed them stretching my fingers or pincer to the back of the tank behinds the plants (With sinking bits).

They are not coming out even if there is no one infront of the tank. Any advise what can be done?

Thanks in advance.

1. Are you sure they are still alive?
2. Check if you have a very strong current blowing the front?

Confirmed still alive. I can see them from the top. All happily hiding at the back. I can also see them fighting to pick up the sinking bits that I fed them at the back.

I have also set the outlet of my canister to blow slightly against the wall pointing towards the back of the tank. This will cause result in the current at the back where they are hiding to be stronger than the front but they are STILL hiding. Haiz.....

I've also experienced this with Galaxy Rasboras. They only come out when you're not standing near by.

How long have you had them in this tank?

Try sneaking up on them or watching them from a distance. Wow you have 40 cardinals in a 2ft tank?

My 10 Jumbo (XXXL) is there for a month now.

The 30 (XXL) addition is there for about 2 weeks.

As long as the circulation was water quality is good, 40 Cardinal in my 2 Ft tanks is doing fine. Plants are pearling and the Cardinal are active when fighting for food. Observe that they are pretty rounded and have nice bright color so no sign of stress or under feeding.

But I just can't see them during non-feeding time.

I was pondering between Rummy nose and cardinal when I was decided to add fishes to the tank. Regreted, I think Rummy nose will have a higher chance to be seen as they are more active and a much better schooling fish.
