Aquarium Fish Led Light Kid Friendly Small Fish Three Divisions Breeding Isolation Mini Aquarium komplettset LED Acrylic Box Betta for Small Fishes()

I have raised betta fry, and used these tanks as isolation cups for the males and some of the females. I love the undergravel filter but I do cut the lift tube about 1/2 inch so I don't need to have the water level so high that it leaks out the hose grooves, and still forms surface bubbles from the spout. For tropical fish such as Bettas you really must have a heater (water temps of at least 78F). I also add a small air stone to the opposite side of the lift tube/spout. The lights are nice, but not always reliable. I've had trouble with the switches. Out of 12 tanks currently in use, two of them have iffy switches where I have to jiggle them to get them to stay lit. Battery capacity is 4 AAA, but it will light with only two. Both of the tank-separating barriers have slots in the base insert, and there's notches in the top of the tank to hold them in place. The fish never hit their lips/eyes on protruding plastic edges if they are removed. These tanks must be well padded and shipped carefully because they often arrive damaged.

The design is good. I even kind of laid out measurements to see how big this thing would actually be when it got here. Once it got here it was a lot smaller than I had thought. I'll give it a try anyway. It's a three compartment aquarium with dividers and I have three betas two males one female. Hopefully this will work for them.

The tank I do not like, simply for the fact it can hold 3 bettas, however the top of the tank have slots for feeding on both left& right side for the bettas.as for the poor beta on the middle of the dividers you have to open the top up everytime to feed.
