Do you want to breed your guppies? Maybe you have a pregnant female, whether you wanted to breed or not. Either way, did you know that mothers and fathers will eat their baby fry if given the chance?
Yeah, it definitely doesn’t bode well for guppy fry survival rates. However, this is where the breeding trap comes into play. Today we’re here to help you find the best breeding trap for guppies (Tom's Aquarium Nursery is our top pick) and provide some helpful information on how they work.
About Breeding Traps & How They Work
Breeding traps are super simple tools that you can use to isolate a pregnant mother fish to keep her safe. However, the most important aspect of these things is that they allow fry to be safe as well. Guppies and most other fish will usually eat their fry if given the chance.
Breeding traps come with special slits and V-dividers, so once the fry are born, they fall through the slits and are kept safe from the cannibalistic parents. Some of these breeding traps can house 2 pregnant mothers and their fry.
They can be mounted either inside or outside of the tank, depending on the model, and it if it is an exterior version, will need an air or water pump for water flow requirements. Other than that, there is nothing special or super important about fish breeding traps.
5 Best Breeding Traps For Guppies
Here we have what we think are top 5 breeding traps. Let’s take a closer look at each of them in some detail right now.
1. TOM Aquarium Baby Nursery
The TOM Aquarium Baby Nursery is relatively small, coming in at 6.3 x 3.7 x 4.6 inches, but it is more than large enough to house 1 or 2 pregnant guppies and/or their offspring. This thing is made of high quality plastic, and as long as you don’t drop it, it should be fine.
It’s pretty durable all things considered. You can place this item in a separate tank, or if you have a large main tank, you can place it in there as well. It comes with many side vents to create optimal water flow and oxygenation, so there should be no problems in relation to those factors.
What is neat about this thing is that it comes with a center divider so you can isolate 2 pregnant fish from one another if needed, or just keep one in a large and open space. It also comes with V partitions to offer maximum safety, both to the adult fish and the fry.
It even comes with a built in filtration unit, one that can be moved from one side of the nursery to the other. It’s not very powerful, but it should do the trick. You can also use this as an isolation tank for injured or aggressive fish.
- Good size.
- Good partitions & divider.
- Included filter.
- Filter is not very high quality.
- Gaps at the side may let fry out.
2. Lee's Two-Way Guppy Breeder
This is a very simple and straightforward breeding trap for guppies. In terms of mounting, simply place it in the bottom of your tank. It does not need to be mounted on the wall of your tank, which does make things a bit easier.
When it comes to size, the Lee's Breeder in at 7 x 3.2 x 3.5 inches, which is pretty decent for guppy breeding purposes. It’s large enough to do the job, but not so large that you will need a totally separate tank for it.
When it comes to quality, it is nothing special or overly durable. It is made out of basic plastic, but should do fine as long as it is not dropped. This thing comes with many side vents to make sure that the fry and pregnant fish have lots of water flow and oxygenation for optimal water conditions. It also comes with a V-partition divider which can be removed or put in at will.
This means that you can isolate pregnant fish for their safety, and it allows the fry to have a safe place to rest and grow as well, a space where they will not get eaten. You can also take the mother out, remove the partition, and let the fry grow in the breeder trap until they are large enough to handle life on their own.
- Space friendly.
- Has a good divider.
- Good air flow and water flow.
- Durability is a bit questionable.
- Not too much space for a pregnant fish if the divider is present.
3. Marina 3-in-1 Guppy Trap
What is interesting about this particular breeding trap is that it is said to be a floating breeding trap. In other words, it will not sink down to the bottom of the tank, and should float at the surface. Yes, this does sound convenient, but beware that if you don’t attach it to the side of your tank, it can float around from side to side, and in all honesty, it does not float very well at all.
It is not overly large and comes in at 3.2 x 6.5 x 3.2 inches. It will save space in a tank, but it is too small for anything other than guppies or fish of a similar size. Just like the others we have looked at, the Marina 3-in-1 Guppy Trap is made of basic plastic.
It is not overly durable but should do fine as long as you don’t drip it from far up. On a side note, this breeding trap can be used as an isolation unit for overly aggressive or injured fish.
Furthermore, this item comes with good venting on the sides for water flow and oxygenation, which is beneficial. Finally, it does come with a v-insert divider to keep the pregnant females separate from one another if needed.
It has slits in the bottom to allow the fry to fall through so they do not get eaten by the parents. However, some fry, the smaller ones, may fit through the very bottom slits and end up right in the tank.
- Good for smaller tanks.
- Great divider.
- Good ventilation.
- Smaller fry may fall into the tank.
- Does not float as well as advertised.
4. Marina Hang-On Breeding Box
In terms of breeding traps, the Marina Hang-On Breeding Box is definitely a unique option to keep in mind. The reason for this is because it is one of the few that actually hangs on the outside of the tank.
It is not very hard to mount and comes with all necessary hardware to mount it on the outside of the tank, but it does need to be mounted, unlike many other breeding traps out there. This breeding box is fairly large, coming in at 5.8 x 10.7 x 5.7 inches, but then again, it does not take up space inside of the tank.
The trap itself is more than large enough to house 2 pregnant guppies, or even some large fish as well. This item can be used to isolate injured fish if needed, although it is not recommended. What you do need to know about this thing is that you need to use either an air or water pump to keep new water flowing into the tank, and to allow old water to get out and be filtered by your main filtration unit.
This is something that can make installation a bit of a pain in the neck, and on a side note, this thing is quite loud and tends to make sputtering noises. It does come with a V-divider to keep 2 pregnant fish apart, and slits in the bottom of the divider so fry can get away from potentially cannibalistic mothers.
- Doesn’t take up room inside of the tank.
- Good size to keep pregnant fish comfy.
- Has a good V-divider with slits in the bottom.
- Does not require much in terms of mounting.
- Requires an air or water pump.
- Some fry may get sucked out into the main tank.
5. Fashionclus Breeder Rearing Trap Box
This final option here on our list today is very simple and straightforward. First of all, this is an interior breeding trap. Simply use the included suction cups to mount it on the inside of your tank. It does not get much easier than that.
With that being said, the suction cups may come undone at times and cause the Fashionclus Breeder Box to sink. It’s a fairly large breeding trap, coming in at 3.74x2.75x5.12 inches, and it has more than enough room for 2 pregnant guppies.
It also includes a V divider so the fry can get away from their parents, which helps to prevent them from being eaten. This thing is actually made of really hard and durable plastic, which is a bonus no doubt.
However, there are slits in the bottom of this box, ones which may allow smaller fry to slip through, but these and the side slits are necessary for water movement and ventilation.
- Easy to mount.
- Enough room for 2 pregnant fish and fry.
- Takes up a good deal of space in the tank.
- Suction cups are not the best.
If you plan on breeding your guppies, you would be wise to get a breeding trap, or else most of the fry will undoubtedly be devoured by the parents. We would definitely recommend looking into one of the options which we have reviewed above.
