It is not a question on illness i think - it is a question of what to feed (i think) d50. It has lost the red on the face and he wants to know how to restore the colour. We had this conversation not so long ago about red in apisto.The translator tool doesn't help much and I don't speak Polish.
Would you be able to fill out the emergency template (copy, paste in this thread here and fill out) and post a picture of the fish?
Template for disease/parasite/death cases
This template contains the most important questions to be answered when dealing with sick or dead fish to find causes and advise on treatments. Please copy and paste into a new thread and answer the questions as precise as possible. Water parameters should be given in numbers. "Fine" or "good"...apistogramma.com
Yes me question is about food to make your red faceMyślę, że to nie jest kwestia choroby - myślę, że to kwestia tego, czym karmić d50. Stracił czerwień na twarzy i chce wiedzieć, jak przywrócić jej kolor. Niedawno rozmawialiśmy o czerwieni w apisto.
Nie chcesz wiedzieć, jaki bełkot z tego zrobił tłumacz.
Dopóki OP nie wyjaśni, po prostu poczekam.
