I never have a paros jumping out of my tanks when Bettas and killies do it often unhappylly

I have a pair in a tank and yesterday I sax a young fish of 1.5 cm swimming.I never saw the male mouthbrooding.The pity I have only one fry

Very good and I will askA.Sahal about the location.I keep my fish in water 80µS and ph 6.I will lower the pH and increase the conductivity of the wate...

Can you tell me more how to set up the tank,water quality and temperature please.Where from do they come?What kind of biotope?I can't find no informat...

I receive 2 pairs and they are great fish.They have to settle a bit to get their true colors.They are 7 cm long
