Review: This hatchery can be used to separate for an aggressive betta - Although I don't prefer to cage a fish, so far, this hatchery seems a working solution to housing a betta and a gourami in the same tank. My half-moon betta was added months after the tank was setup. The betta didn't bother the sterbai corycats, neon tetras, or the siamese algae eater at all. But anytime it saw the little honey gourami, the betta would set it's sight and chase the gourami around the tank. I could almost hear the music from Jaws playing in the background! The hatchery comes with dividers, but to maximize the space available for the betta to swim in, I leave the dividers out. I like that the hatchery is a decent size and that using the suction cups is optional. The design of the hatchery allows it to float and in my tank, it stays in one place without the use of the suction cups. The betta seems comfortable. The honey gourami is happy. I give this hatchery two thumbs up. All is well.
Review: Nice fish hatchery - I have now purchased two of these fish hatcheries. I use one for babies and another to quarantine a wounded fish. It comes with suction cups to hold it in place, but it is pretty stable without them. It also has a divider if needed. It’s a quality product and a good value for the money. I planning to add a couple more to my collection as my African Cichlids continue to multiply. I definitely recommend this product for any fish keeper.

## Questions & Answers

**Q: Does this share water with the main tank?**
A: Yes  it goes on the inside of tank. I leave the top of mine about 1/4 inch above the water level in main tank & slide the lid to one side so I don't have to take it on & off to feed the baby fish & so they don't get out.  I'm on my 3rd set of baby fish . The suction cups hold really well but you can slide it up & down a  little bit if you need to  & it stays in place.

**Q: Can I use the medium or large to breed my zebra danios and tetras fish?**
A: I think you probably could if she's comfortable laying eggs in there. My zebra is getting ready to drop her eggs soon and I'm trying to get her to do it in one of these now. I got the large and there's a pretty decent amount of room in there for my pair to swim around and hang out.

**Q: Can you use it without the divider once the mom is removed? I am looking for a larger plastic in-tank cage to let my platy babies grow.**
A: of course you can, it is 5.2*2.7*2.9", you need to keep an eye on the babies, once some grow up, you need to remove it out of this breeding box in case it is too crowd.

**Q: Can I remove the isolation board (the one that stands vertically on the inside)?**
A: Yes it is removable

### ⭐⭐⭐⭐ Can be usable with the right imagination....
*by J***S on April 21, 2025*

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.
