I am a englishman living in suwalki in the north of Poland ,In june i set up an existing aquarium for peacocks and haps and stocked it up,i bought from a man who seemed to have a good selection of fish. I recievded the fish on the bus after about 8hrs and out of 26 fish only had 1 fatality which he replaced. I quickly realized my tank would not be large enough so i bought a 200x60x60 720 Lts and set up and changed over using my existing filters and 50% of the old water,no problems .the problem i am having is that i bought all males and although i have some beautiful fish some of them look to be females[6]now the seller has said he did the best he could but the fish were small, a local petshop has said he will take the females but at a fraction of what i paid for them. the good news is i have found a wholesaler who deals with a German breeder where i can see the quality of his fish online and he guarantees the sex of the fish.Is this a common problem in the cichlid fraternity or have i just been unlucky, by the way the fish were not cheap thankyou.
