what does it mean when an apistogramma just lays on the sand?
One more thing..Too much circulation (Oxygene) may stop your plant from thriving+growing OK../Micke
I agree with Mick on nearly all things, but that isn't actually true. More circulation usually increases the level of all dissolved gases in the water, by creating a larger gas exchange surface. This means levels of dissolved gases are more similar to levels of atmospheric gases.you know I never thought of too much oxygen would decrease plant growth man that makes total sense
Mick is right, rheophilic fish are particularly at risk from the Root Effect, and it was the "symptom less" death of large rheophilic Loricariids that led me to write <"Aeration and dissolved oxygen in the aquarium">, based upon the work I'd done on the re-mediation of landfill leachate.The Farlowella`s would probably love it though.
If your weak Apistos are swimming slowly in a S-shaped way and the problem spreads to the other Apistos, they may have flagellates internal (causing Hole-in-the-head-disease on Discus-fishes).. One other symptom will often be white soft feces+ fishes getting thinner belly/stomach over time..even if they keep eating OK.. But do not medicate (unnecessarily) if you are not sure of this!!
My 1st thought is that the Mcmasteri`s + dominant(larger) borelli`s probably are bullying the weakest..in order to establish the hierarchy+territories in the tank!! (Borelli is one of the most "friendly" Apistos..Mcmasteri gets bigger and are more competetive..at least in this situation!!)
I'm not sure whether your borellii will ever be able to co-exist with the 4 macmasteri, even in a big planted tank.I will see what works best with our making the fish uncomfortable. So far they are good minus just 1 borelli that just isn't adapting
I'm not a chemist either, but looking at water parameters in polluted water is part of my "day job".Thanks for the corrections Darrel.. Since I´m not a professional chemist I sometimes may phrase things in a wrong way..
Yes and no, it largely depends upon tank architecture (volume to surface area ratio) and the bio-load (including the sediment).What I actually wanted to say was that the ammount of CO2 may drop if circulation is high/strong.. Correct!??.
