Petzilla In-Tank Aquarium Breeder Box: Perfect for Fish Tank Breeding and Small Fish Hatchery

Kendra rowin: Man, I knew it was gonna be small but it’s small small. Almost too small, it gives zero room for any kind of growth in it and the fry would have to be immediately moved to a bigger net.

Fryre T. Tuck: I purchase this box because I knew I had two fish who were going to give birth soon. I put the mothers in one tank and had this one for the nursery because of its small size. But the suction cups would not hold onto the side of the tank. They kept releasing no matter how hard we push to hold on. The first night the nursery was full, the box pulled away from the side sometime during the night and floated under the waterfall in the tank. The waterfall caused the tank to sink and in the morning all the babies were gone. We searched the tank for the baby fish and decided they had become live fish food for the other fish.
Beware of the the suction cups. They are not strong enough or reliable enough to hold the box to the tank wall.

K. Gast: Perfect small isolation tank - suction cups failed after just three weeks - make sure to buy better ones separately.

Marie Lee: First I never expected it to be that small I should have read the reviews before purchase.
Second one of the black suction thing broke it was so hard to put in the slot and sharp it sliced it and the only good thing about it would be no babies could fall out of it. The top was just kotch on the top as with black suction thing it was not able to sit down properly buy the large one so to give the fish some space toove around

Bookworm: This is quite small. Note the measurements before ordering. Ok for what I needed. Plastic is thin. The suction cups work fine.

Briany TzuHung TaiBriany TzuHung Tai: Great for a little fish to be in there, but I found it too small. I can barely put my hand inside to grab the divider out.

One of my question before purchase is that, would the new born fish escape the breeder box from those vertical gaps. The answer was absolutely they DO NOT escape.

I also wished the suction cups wasn't back but in clear.

When i have two female guppies in there, the bigger will chase the smaller one, so I might have to upgrade to two side breeder.

Patrick grondin: Les ventouses ne tiennent pas bien comme tout les ventouses dans de l'eau il faudrait un petit crochet pour la maintenir en place ce serais beaucoup mieux .La dimension est un peut petite pour le temps ou la femelle attend ces petit.

Julia MarieJulia Marie: I got this extra tank to hold feeder fish in for my piranhas. It came in a pretty questionable-looking box that looked fairly weathered and worn. I was a little hesitant to continue opening the box since it looked so flimsy and strange, but I had to get to the mini tank itself. The mini breeder tank looked used as well. It had some odd residue on the sides of it, and overall it just appeared kinda crumby. Nevertheless, it does work for what I need it for. I wasn’t looking for anything fancy, so this is actually suitable for me.

However, the plastic is super thin and cheap. It’s a rather flimsy tank itself, and the suction cups honestly suck. No pun intended. It is always coming loose from the side of my aquarium, and comes off of the little tank unit itself very easily. The way that the suction cups are fitted onto the breeder tank are kinda dumb in my opinion. It makes them come off a lot easier, which isn’t necessarily good.

Anyway, this tank works ok for what I need it for. I don’t know that I’d recommend it for anyone who’s seriously considering it for breeding though.

LauraLaura: This has worked perfectly for us! I did read reviews first. Lots of them and they are very accurate. The large is VERY SMALL. if you are using this to catch the babies when the mom is birthing them I would say this is only good for fish around the size of guppies, platties or mollies. It is extremely small. I woke up and saw babies in my tank and ordered this with same day delivery. I caught them and put them in here so the mom was never in here. I did put gravel in the bottom as suggested in one other review and I also put some java moss in to help them hide and feel safe. I'm very pleased with it. For me the size is perfect but if you have a larger fish and you're breeding on a regular basis this probably is not something you dont want to purchase. This is in my 65 Gallon tank. I gave it 4 stars because of size. I can't imagine what the small one looks like. To me I would consider this a small if I'm thinking about small, med and Lg sizes.
