Fish Breeding Box, perfect fish tank divider acclimation box for aggressive fishes, nursery for injured, hatchery incubator breeder box for Shrimp...

I have large African cichlids 5-7 inches. I use this to seclude fish that are being attacked by their tank mates. Its a nice big size & floats very well in the tank, no tipping. However, the lid does not snap on, so when the tank is submerged with the use of the suction cups the lid comes off! I put a rubber band around it to keep the lid on, but there is no hole in the lid for feeding so that didnt work for me. It does float slightly above the water level so the fish cant escape even without the lid. I would recommend this tank as long as you dont want to submerge it in your fish tank.

It works ok. The middle divider tends to float which is a little annoying but not game breaking. It will float but I left it overnight without the suction cups and it had sank by the next morning. The suction cups work well and were very strong. I pulled the box off the cups before the cups lost suction. So itll be better to use it that way if you want to keep your fish inside it. Another thing that could have worked better is being able to remove the box from the tank and it retain enough water to be able to Dump the fry in a new spot. All the water drains and my guppy fry were stuck the it. It was nerve racking but everything worked out. Good enough for the price anyway I didnt loose any fry

I want to start off by saying I'm using the breeder boxes to hold my pothos and other plants- not for baby fish. I place them under the outtake of the filter because that is where the aquarium lid has holes to poke my plants through. SOMETIMES, it tends to fall to one side, which is kind of annoying but I suspect it's simply because it's under the outtake flow which is pretty strong. I have 2, and both have clay substrate in them which can be a bit heavy. Both hold up very well, so if you are just housing fry this works extremely well. I have used them for molly fry in the past and it was very reliable. I have also used this box under my outtake to buffer the filter flow for my Betta tank. I put a sponge and some plants in it, and the flow was reduced significantly without hurting the filter at all. In short, it's very versatile and holds up well.

As advertised. Strong section, had to use butter knife to release

My baby mollies have lived in the breeding box for two months now, protected from mom, who would have eaten them if given the chance (as she did their siblings, RIP). I don't recommend keeping more than a couple fish in here, as it is quite small, and make sure the water level is high (do water changes in your tank weekly). I'm still feeding them First Bites fish food daily, and keeping their little tank clean. It's perfect for these little guys until they are ready to join the rest of their tankmates!
