Multies Not Spawning
« on: January 09, 2018, 08:28:32 AM »
Hello everyone.

I've had my 6 multies since March 2017 and they haven't spawned yet. They live in a 20 g long tank and I believe I have 4 males and 2 females. The substrate is covered with shells (there must be 80 - 100 shells, mostly escargot) so there is no lack of spawning sites. There are two Julies in with them but the Julies don't stray from their rocks.

I know I'm supposed to be patient but 9 months seems like a very long time when I read posts about multies spawning within weeks or a couple of months after adding them to a tank.

Your thoughts and recommendations would be greatly appreciated.

Thanks.

If you got them from a local fish store most likely their all male. At least thats what mine did.

Yeah in my experience females are a lot smaller than you'd expect so you might have all males.

Sure, patience is crucial in this hobby. But I think patience often gets associated with passivity. IMO, that's a mistake. For the sake of brevity I'll assume excellent water quality and nutrition. I'm also going to assume your fish are sexually mature and in good condition. And at 9+ months of age, I'm also going to assume you have accurately determined 4 males and 2 females.

I went back and did a quick review of your other posts. IMO, you've already toyed with the idea that first comes to my mind...get another 20 long and separate the multis and Julies. Pending how the multis do with more elbow room, I'd consider reducing the number of multi males.

Thanks for all the responses.

The two that I think are females are a bit smaller than the other four but not all that much smaller. Should the size difference between males and females be so apparent that you would know without having to guess?

It didn't occur to me that my LFS would have only males. I expected that they get their fish from some wholesaler that just randomly scoops out whatever number has been ordered. But now that you mention it, I suppose the LFS could have got these particular fish from a hobbyist that was getting rid of extra males.

I have been lazy and haven't checked the water chemistry so I will have to fix that.

IME, after 9 months, yes, your males and females should be showing enough difference in size that you shouldn't have to guess. And it's not a matter of a couple millimeters. Your males will be longer and taller than your females by a clearly visible difference. Pic isn't the greatest but maybe it will help. (Extra notes: female on right is extra dark b/c she's on a recent spawn, fish just to the left of the female on the left side is a juvenile male.)

That pic is really helpful. I clearly have all males.

What would you recommend to fix this situation? Should i just go back to the LFS and get another couple of fish, hoping that i het females?

Well, bummer. I'd say it's worth at least approaching them with the conversation. Really, anything you can do to improve your odds of getting females instead of males would be the way to go. :)

When it happened to me i specifically asked for 1 male and 1 female then they said i need at least two females. I went ahead and bought two more the following week at $28.00 dollars a piece. They where all adults. 6 months later no fry.
I had no idea that the females where so small. Thank you for posting that pic. I bought 7 more off aquabid and it looks like at least 2 or females. Hopefully i get some fry.
