Is there a specific Epsom salt brand I should buy?

Hello folks, I ran to a problem after my male medaka rice fish did his first spawn. His male organs are sticking out and idk if there's a solution for it? Water is fine and never had a problem until he try to spawn. He was successful and places the eggs on plants.

Yep! Weirdly, I don't have to do any cold water changes to trigger them to breed. I give them blood worms or tubular worms and they would spawn the next morning.

Update, I FINALLY HAVE EGGS AND BABIES! I was doing some spring tank cleaning today and found few eggs on plants. Im pretty confident there are more somewhere in the tank. I think the problem was the females weren't mature just yet. The females have double in size since my last update.

Update I sat up all morning watching my Corydoras do their mating dance and T-shapes. Lol the males definitely into the mating. They were bugging the fat females, but my female didn't seem to care and didn't lay any eggs. 😂

Update Im gonna try to do 2 male and 1 female in a breeding tank to see if I have better luck.

It could be that they're eating their eggs? I guess I will have to sit and watch them finish. Their tank started to clear up now. I'll also double check the plants too. 🥲 Corys are harder to breed than I thought.

Update, Still no eggs, separate the adults from the tank, but no babies and no eggs. Added them back into the tank. I have recently try 90% water change with cold water. I check all the added plants in the tank. I didnt see any eggs. Now im doubting that I have a male out of the 7 that I have or im just having bad luck. 🥲😔

Should I be worried? For example, My white cloud minnows always seem to co-exist and breed with the scud in their tank.

I know from a lot of breeders that said that scuds and red cherry shrimp eat fish eggs? I have never ever seen them eat them. I have seen them clean them and toss them aside after they clean them. Is that weird behavior for them?

Im crossing my fingers that another breeder can share their advice 🙂🤞

Yes, I have watch these videos 🙂. I actually watch these before getting CPDs. The videos are nice, but it just doesn't give me the answer of why they arent having fertile eggs. Great information about setup though.

Interesting, I might increase my male count because I don't think have 2 males are doing their job. My females are definitely laying great number of eggs.

Im starting to run into that problem too. The first spawn was great, I had 10 fertile eggs that hatch and are healthy. All the other attempts have been very little fertile eggs and lot of unfertile. Here's my setup. I have a java moss in a plastic container in the back where they spawn in. Every morning I would take it out and grab the eggs. I also have a heater that keeps it 72F-75F. I have 7 CPDs, 2 Males and 5 Females.

Any tips how to reduce the number of infertile eggs? I have notice that my CPDs eggs are turning out infertile. There'll be 2 fertile eggs for every 10 eggs.
