capetsma Fish Breeding Box, Acrylic Fish Isolation Box with Suction Cups, Aquarium Acclimation Hatchery Incubator for Baby Fishes Shrimp Clownfish and Guppy... Small Size (S)

Works as expected. Good value for the money

Funciona perfectamente

a bit small, like doll house small, but I did find a use. I have Beta baby fry and sponge filters are a nightmare for me. So I have a 5 gallon tank filled halfway and I placed a Whisper internal filter inside the clear breeder/container still using the plastic fall thru to lift filter. It uses a med cartridge. Put it on slow flow. Maybe you can find a filter for your needs using the small size. Water is noisy like a water fall, but I don't mind. Helps my babies not get sucked up from using the bigger filter and keeps the tank cleaner.

Absolutely perfect for guppies. I have had trouble finding something with small enough slots that the fry don’t fall through and this does the trick. I have 2 of them in a 10 gallon for my 3 females and it’s perfect. I also like that it actually fits together; some of the breeding boxes have floating interior parts and this doesn’t.

This is a fairly decent product. My only issue is that the wholes are too big for my danio eggs/embryos meaning they can easily escape into the main tank quickly drawing more attention to the box and ultimately becoming prey.Once I saw the fish swarming around the box and saw one escape all I could find to quickly resolve the issue was wrapping a clear plastic shower cap around the sides and bottom.It helped but now I have a few tiny fry stuck between the cap and the box :-(Honestly, with the large, I wouldn’t even put a few day old black mollies in there.The box is great for isolation of bigger (youth/adult size fish such as mollies, guppies, etc) though!! Just be careful if you choose to actually use it as a “breeder” box.At one point, I even had black mollies eating the contents of the box through the holes on the side :-(

I bought this for guppy fry that were getting too big for the dinky little breeder box I already had, but were not yet big enough to move to the six gallon aquarium I had set up as a grow-out tank. (When you put them in too big of a tank too soon, I find that they waste a lot of their energy for growing while looking for food, exploring, etc.). This box gave them twice the space of the old one, maybe more. Very easy to clean. Like most boxes of this kind with the slits on each side, I don’t trust it to provide adequate water flow. For this reason, I lift it halfway out of the water once a day to make sure toxins are not building up in the container, and let some of the uneaten food and poo flow out. The babies were a little confused by this initially, but it doesn’t really seem to stress them out. (They’re only a couple of weeks old- at this point they just think it’s normal to suddenly have half your water disappear for a moment. What do they know? Lol.). I also put a wad of Java moss and some hornwort in there so that probably two-thirds of this was basically a jungle on their scale. I highly recommend putting plenty of plants even if you just use fake ones- otherwise the bare empty container will stress the bebbies out. Finally, I put a ramshorn snail in the container to help clean up- like having a Roomba under the high chair, haha. The babies were fine in this box until about three weeks of age. They are now in their grow-out tank and doing well.I have not tried this to separate mom from babies, yet. The next lady to go into labor gets to try out the new maternity ward. But I would not even try it in anything smaller than this because putting them in tiny containers stresses them out a lot. This one, with plenty of plants in it, is large enough that it might be worth a try. I’ll update this review after I see how that goes. But, just as a nursery, this is a great little box.

Save your money on this cheap Chinese garbage!!!! Suction cups do not hold, you could walk by and fart and it falls, the top floats away with No locking mechanism, it just sort-a fits uOn top. It was cracked out of the box and required modification to even sort-a function. Had to use my maga-a-float to keep it on the glass (magnetic), had to put a rock on the top…… save your money, get a Tupperware container/ drill holes and use and aquariumMagnet. This cheap 10 cent Chinese POS was garbage.

Kept the little guys safe from getting eatened, easy to get together.
