I’ve recently become the new owner of a group of six CPD (3 male, 3 female). I work at a local LFS, and one of our fish suppliers brought them in instead of the Harlequin Rasboras we’d wanted; oops! Well, I didn’t want them going to someone who wouldn’t appreciate them, so I set up a tank for them myself, and they are living quite happily in my bedroom.
Here’s the set up:
10g tank
I ended up cycling it for four weeks (I borrowed one of my many bettas), as I couldn’t get my hand on mature filter media, and I didn’t want to take any from work (ew). It’s also divided; about 1/4 of it is reserved for the fry. I know that’s not a lot of room, but I’m not looking to breed four million babies, and I am willing to make as many water changes as required.Substrate: Flourite (regular red)
Temperature: 23C
Ammonia: 0
Nitrite: 0
Nitrate: 32 ppm (I usually change the water when it reaches 40 ppm)
Filter: Whisper Canister 10-15g (I’m very cheap), with added sponge behind the filter cartridge for greater surface area for bacteria.
Plants:
Val. Corkscrew (very tiny one, so far)
Acorus
Java Fern
Crypt. Wendtii (bronze var.) x2
Plants I will be adding this week:
Java moss
Barclaya longifolia
Watersprite
Water Lettuce or Giant Duckweed (I haven’t made up my mind yet)
Light: 6500K Fluorescent
Food: New Life Spectrum Small FIsh, Hikari Mini Pellets, SFBB Variety Pack Frozen Food. Tthey really like the bloodworms- I chop them up very fine- and the cyclops. Two of my males really like blanched broccoli, as well (I was curious, lol); it is okay for them in tiny amounts?I’m fertilizing with Seachem Flourish. So far my CO2 is fine, but with so many plants, I may set up an injector later.
Now, I have a few questions. Should I attempt to spawn the fish in the part of the tank I want to stick the fry, or just let them go at it in the larger portion and siphon later? If I leave them be, should I siphon the eggs out, or just the free swimmers? Should the Java moss be in a big clump, or spread out in a carpet?
Should I see if someone is willing to trade me a female for one of my males? Wouldn’t a better breeding ratio be 2m:4fm?
And, how in the world do I tell when a female is ready to spawn?
I’ve only bred guppies before (which was almost embarrassing, because I never had to do anything special), so most of this is new to me. I know these questions have probably been asked a million times before, but I’m having a hard time fining the answers on this forum. That’s my excuse, and I’m sticking to it!
Hi Lissa, welcome to the forum!

Your tank setup sounds fine.
You want the moss to be arranged so they can burrow into it. I usually just keep mine in a very large ball, about 1/4 of the tank.
You’ll notice your girls being chubby. It’s kind of hard to explain, but they will look well rounded when compared to the males.
I never had much luck raising any fry until I put a trio into a completely overgrown 10 gallon tank. They are easy fish to get to spawn, but they will eat the eggs and the fry almost as quick as they produce them.
I just started a tank with guppy grass floating above java moss that takes up one half of the tank. I’m hoping the fry will stay on the planted side until I can remove them.
Also, I always move the fry into a grow-out tank that is full of java moss. Simply catch them in a small cup, I use an empty yogurt cup. They are very fragile and don’t take well to netting.
Hope this helps, and good luck with your breeding project!
