Hi, I've had my 14 gallon biocube up for about 2 years with my clownfish wich I've had for about 4 years . I always wished that I had put two in together but I decided not to. Now I'm wanting to know is it ok to introduce a much smaller clownfish to go with the other? I understand the male/female issues with clownfish but don't want to add another one just to have it killed by my older mature clownfish.any info would be helpful thank you in advance!
