how common is this lol??? ive just moved my 2 goldfish into a bigger tank about 3 days ago. since thenboth been acting really wierd etc, then when ive just gone to look see how they were doing, the tank is covered in eggs lol!! all over the logs n ornaments etc....10000% sure now that they are actually goldfish eggs, cos i just seen a big shower of them being dropped from the fish lol! now i dont even know which is the male + female etc, have never really looked into it cos i had no plans 2 breed them lol!! and also, they are 2 diff types of goldfishImage


can anyone tell me anything bout this?? is it being 2 diff kinds gonna cause problems?? and if i wanted to try raise a few babies, do i need 2 remove the eggs etc from the main tank???

I know it happens quite often in ponds, but I'm not sure how common it is in aquariums. I assume the change in environment to the larger pond was the trigger for spawning. In ponds, spawns happen in the spring when the water is warming up, so the upgrade may have somehow mimicked this change.

I think removing the eggs would be a good idea. To my knowledge, goldfish do not care for their young in any way and may eat the eggs or fry. I'd set up at least a 10g with a sponge filter. I'd google goldfish fry or look up a goldfish forum (Aquaria Central has a pond as well as a coldwater section that might have a thread covering goldfish fry rearing.

actually, you are supposed to remove the parents not the eggs. Try not to expose the eggs to air.

Now.. the question is if the eggs are fertilized or not. Only time will tell.

Must be catching up here :lol:

I changed a few hundred gallons on my outdoor pond last night, adding cold tap (and an entire bottle of dechlorinator). This morning I went out to check on the rabbit and the goldies were all spawning 8) Comets, commons, shubs - all of 'em.

Oddly, the girls at the front of the pack were 'scraps' a fish who once had no tail due to finrot and a white tripletail who's about fifteen years old!

The koi were following them around, eating the eggs, so I managed to net some and transfer them to a tub that I have a small water lilly in and loads of cyclops. Maybe, maybe, there will be some hatchlings but I won't hold my breath. I was careful about not exposing to air - netted the eggs straight into a jug. If any do hatch, there will be a huge quantity of natural, veggie gut loaded live food for them. Some of these cyclops are smaller than baby brine shrimp 8)

congrats on the babies :)

I tried something similar but my eggs were really fat and sticky. I would have had to move the parents.
