Hi all having returned to the hobby after some 40years when the hobby took over my life travelling the country showing fish I see something for the first time . A pair of unknown apistogrammas 4weeks in thier new 5ft home , the pair were feeding well water conditions are good . Ths male was showing his fins to thier full when infront of my eyes he started to spiral out of control ending up on his side at the bottom of the tank . He never recovered. Why? Anyideas Regards Slimjim
