I have a 30litre biorb with heater that i have just kept guppies in. I bought a new female who gavd bith a few weeks later and died. she had 8 fry all survived, they are about 3 months old now, so they are all pretty grown. I have one baby that has a very prominantly bent spine and is much smaller that the others.
I have read in many places that you should euthenise bent spine fish, but have never been able to contemplate it. and he seems to eat and swim pretty well with the others. but as they grow he becomes more different.
I just wanted to know wif anyone elsehas had similar fish. Im very happy to give him any extra care he needs, even if he needs his own tank if he cant compete. but i would hate to have him suffer. I know 8 guppies is pushing it for 30 litres. So far i cant tell the sexes
all comments welcome.
