hi! i love to take care of fishes since i was in my gradeschool and i had encountered many types of fish, but now i have decided to take care of a goldfish and i now have 1 large common goldfish, 3 medium common goldfish, 2 nishiki koi, 2 small r/w comet, 2 small long fin koi, 2 mickey mouse mollies, 1 neon blue molly, 1 silver molly, 2 neon tetras, 2 glowlight tetras, 1 metallic blue guppy and 4 red tailed guppy...btw i have a 8 goldfish fry...

i would like to know if i should separate the fry from the unhatched eggs? and if i should replace the water because its getting dirty...

This is probably a stupid question, but all those fish aren't housed together are they?

If the unhatched eggs are firtile, it's ok to leave them there. If they're not firtile, you better take them out. It's ok to do a slight water change. Just make sure that the water you're going to put into the bowl has been sitting for a day or two with conditioners. You can use an air hose as a syphon and use the air hose again to put water into the bowl.

thanks... its a big help... but sad to say they are down to 3 from 8...
