## Description

As an automatic circulating nursery, the Penn Plax Aqua Nursery and Hatchery will keep your baby fish safe and healthy in a gentle way. This innovative breeding box Nursery draws new-born fry through a tube from the maternity section into the nursery section keeping them separate, alive and healthy. The nursery section may be lifted out separate from the maternity section and placed in other locations.The Aqua-Nursery has a constant circulation eliminating stagnant water, as well as adjustable hangers and removable top covers.Breeding your own fish is fascinating and educational, not to mention cheaper. Now it's easier and safer too.

Review: This thing works, just wish it were bigger - This thing really works. Once you attach it to an airline tube, it really does draw the fry down and into the other chamber. I left a guppy in it one night when I noticed her in labor and woke up the next morning to find the small chamber full of fry. My next attempt will be with a cauliflower sabertail (swordtail) that is VERY valuable. The side chamber doesn't like to sit well though. And most of that is because the tube connecting the two chambers is often too long, leaving the side chamber too far out. So you'll want to cut that tube down a bit so the side chamber sits properly. The lid on the larger chamber also needs to be SECURELY in place, or the fish can freak out, bump it, and knock it off. My only real problem with this (and with many breeder "traps") is that they are so small. There isn't enough room for the poor females to swim around. Mollies and swordtails basically have to stay still the entire time they are in there. So if you don't know *when* they got pregnant, you probably have to leave them in there for days or weeks - or hope you catch them when they first start going into labor. There needs to be a larger version, or perhaps several V-shaped traps can be attached together to fit a particular tank (like a 10-gallon) so the adults have the top of the tank and the fry slip through to the bottom. Aside from the size, this is definitely an efficient way to save the fry of very valuable fish. I'm sure it would work for scattering egglayers too (like tetras and danios) but I haven't tried it yet.
Review: Versatile assembly for different setups. - I read many reviews here and on other sites. It one thing to have good written reviews but this one had videos. So, I decided to go for it. I’m happy this product was sent with lots of bubble wrap and cushioning as I heard the plastic was brittle, but mine showed up solid and intact. I did notice that there was invisible tape holding the lid on, hard to see but had I not removed this I would have cracked the lid. Yeah, it’s made of hard brittle plastic, I guess some boats are more solid in water. Easy assembly with paper illustration even though part A “The Platform” isn’t labeled, but it’s easy to see it’s the only part not labeled. My plastic tube was cut perfectly, test before pre-cutting. Yes, the Nursery and the Hatchery don’t line up well but it’s fine as our hatchery is in the corner so it still sits in place on top of the bubble tube. So far so good… now we wait for babies… It was a partial success, timing is key and fry slip right through the slits in the holding cup, so this only works best in a isolated tank.

### ⭐⭐⭐⭐⭐ Excellent Nursary!
*by B***S on January 16, 2021*

I was a bit skeptical given some of the reviews, but this thing worked perfectly for me. Everything fit together snugly--no rubber bands needed! The only tiny hurdle was that the tube that moves the fry from the main chamber to the side one was indeed at little too long, causing it to kink. Trimmed off the extra quarter of an inch with regular scissors in about thirty seconds. I'd rather it be a little too long than not reach across. And of course watch out for back flow to the air pump since this is likely to be sitting higher up. I put in a check valve just in case and had no problem. I have the tiniest air pump money can buy and the suction was almost perfect. The fry were immediately drawn below the green layer where momma couldn't get at them. One or two made the full journey right away and more a bit later. They have to get right up to the mouth of the tube for the current to be too strong for them to fight, but it was easy enough to shoo the rest through once momma was out, and they were perfectly safe the whole time so I was very happy. This design is excellent. The slits that let water in are very thin, much smaller than they look in the picture because they are tapered from outside to in to encourage flow. This nursery gets excellent circulation and I can't picture any fry escaping. The side chamber is easy to remove--much easier than trying to net a bunch of tiny endler fry, and way less stressful for them! It's been two weeks and I've had zero mortaliy, so this product certainly did it's job. In conclusion, this nursery is a bit of a precision instrument compared to others, but with a little fiddling (almost none in my case) it does a great job ensuring the health and safety of your fry! Beats a box with holes and eagle eyeing your pregnant fish in my book.
