hi,
first of all I have a 300L plantad tank with co2 presurized system, ferts based on EI method, lighting 0,5 W , and 15 rasboras ( heteromorpha) , .... so what is realy interesthing I noticed recently that every time i knock the glass when I am about to feed them ..they go crazy ... yes , sudden movement to the left and to the right but in a very weid way not something common movements..... some of them as they reach the surface for food ...die, yes they die or fall on the plants and die the nezt day ... i already lost 5 fish like this, no idea why they are doing this , it is hard to explain but I've never seen this before.
I mention that shrimps are ok so C02 can not be the problem .. i guess...
the ferts levels N is 20 - 30 ppm and P 1 - 2 ppm , I stared to dose Mg too little by little and few K ,
I always do the same waterchange ( 50 % weekly ) for years and this is the first time i notice them doing this.
Any ideea what is going on?
thanks.
