i had 3 golds now i have 4 all female when i got the first 3 that was a fair bit of time back they were rownd the same size but 2 of them grew alot faster then the third .....the one i just got from the pet store is about the size as the small one of the first 3 i was thinking of when the fry i have get to rownd there size puting the 2 small golds in with the fry so they would be with fish arownd there size so they can be shore to get a chance at geting food with out bigger ones pushing them away so they can get bigger faster and then put them back in the big tank when there near as big as they grew
is there any reason why this may be a bad idear ........oh and i would wait for the fry to get to there size i no if i dont the fry would be eaten
