Apistogramma Cacatuoides frys

[hakan]

Hi friends

My Apisto frys nearly one month old. They are about 15~20 qtys. When they birth they were healty. I am using air sponge filter. Some of frys color changed very dark black. And they mostly standing bottom of aq. I found yesterday one died. I am worry nearly 7-8 frys black. I wonder what is reason. This is my second breeding. This didn't happened first time in summer.

What can i do?

Regards

Hakan can it be the water parameters? How often do you change water?

Thanks Tolga

I am chancing water once in 3 or 4 day.
I tested water paremeters yesterday (Tetra 5 in 1)Results;

ph: 7.2
kh: 6
gh: 10
No2: 0 mg/l
No3: 10 mg/l

The rock in the photo looks like a form of conglomerate - pebbles & sand cemented together (usually) with calcite. The shell is obviously composed of aragonite. Both calcite & aragonite are forms of calcium carbonate (CaCO3). Both will increase your carbonate hardness. Although not as critical with A. cacatuoides, I would still remove them. Often apistos will turn black if there is too much light (from top & bottom) and not enough hiding places.

I have witnessed fry death when relying too much on microworms which come from smelly containers. Do you keep your worms fresh? Don't let the worms go stale.

Thanks Mike and Tolga

The reason shell and rock for frys to set up hiding place. I removed shell and rock immediatelly last night. And change %20 water from my planted aquarium. I dont change with fresh water. In this aquarium very less light because i am using one enerysaver light for two apisto fry aquariums. This aquarium capacity is 30 liter.
Tolga every 10 days i freshly make microworm culture With only bread and yeast. This is more easy and no bad smells.

Is there light coming into the aquarium from the bottom? This can make the fry unhappy. In bare bottom tanks I either paint the outside with black paint or cover it with black plastic.

Light is coming from up, The lamp is up and it is standing between 2 tank. It is energy saver lamp 20W (gives ~100W light)

Now tank required hiding place. There are a lot of empty area. Do i have to increase java moss? Or anything to safe to put apisto frys.

 

[Mizu]

perhaps 100w of light is a bit much for a un-planted tank. You fries will love java moss and hiding spaces.

Thanks for replies

Lamp is only 20 W. Standing on top between 2 frys tanks. Problem now solwed. They are swimming and eating many foods. Many thanks this forum.
