Sudden schooling and staying put

[Akshay]

This is weird
All of a sudden (20 mins after food) all the fish are at rhe bottom part of the tank (not sitting on the bottom) just hovering around 2-4 inches above the substrate
Furthermore they in tightly packed schools
All cardinals ,all rummy noses all rainbows with their own kind
All of them
Temp is 24.8
No ammonia or nitrite

Breathing looks normal
Any idea why this could be happening?

Do you know the co2 level? Sometimes it can cause them to be lethargic if it’s high.

 

[Akshay]

Ph drop is 1.05-1.1 , from 7.3 to 6.25 (from degassed to lights on, rwmains constant through out photo period)
Checked ph , it was 6.3

Ph drop has been consistent for ages
Havent tested the exact ppm of co2 but it should be around 30-35ppm

 

[Mr.Shenanagins]

Did the lights just come on or have been on? Any loud noises or bumps to the tank?

 

[Akshay]

No, 3.5 hrs after light on
I was sitting infornt on the tank , as i always do just before dinner
I Think sudden increase in humidy caused some precipitation on the glass and obstructung the fishes' view & spooked them out apart from that nothing out of the oridinary

After 30nins or so they all dispersed
started with the Rainbow boys chasing the rainbow girls

Well, I know I just want to sit around and do nothing after a big meal.

yes, had gotten a small pc after searching for ages , (around 12-13 months back), it has grown, have now cut it into 2 huge pcs
infact all my epiphytes do really well under really high light , have almost all of them growing at 140 par
