Aquarium Fish Tank Acrylic Divider 5.5/10/29/30/40/55/75/120 Gallon Isolation Board with Suction Cups (Small-1 Layer breeding Box)

I just received this tank divider in the mail yesterday but I was so excited and so happy about it that I figured I would let everyone else know and write a review on it asap. I LOVE this divider (so far). It came decently fast, shipping in only a few days (5 I believe) which was good cause I was really needing it. I had a terrible plastic makeshift divider in my tank because my two rather large fish were not seeming to get along. I was reading the reviews and some people said they did not receive the correct size but mine was perfect. I measured my 75 gallon tank to get the dimensions which was roughly 17x19 and was almost a bit worried when I opened this as it looked a bit large however it fit perfectly. I had to kind of put it in at a tilt because there is a lip on my lid, but as soon as it went under that lip I was able to move it straight and it worked fine fitting right underneath the plastic lip. I did have some trouble when it came to peeling the outside layers off, because I had to use my nail to really scratch at it until I could get a good piece of the film enough to grab and pull the whole thing. Both sides came off completely with no issues leaving the crystal clear divider underneath. I could have actually gone with some holes that were a bit bigger because my fish are rather large, however the holes are a decent size and even medium fish would work well with this divider. I wish that the suction cups were a clear plastic too like the devider itself instead of a whiteish color, because that is the majority of what you notice. But it works well, fit perfectly, and looks great.

Arrived quickly and was packaged well so the plexiglass did not break. There is a film on either side that you HAVE to remove before installing that’s why some reviewers are commenting the glass is foggy. Also as the title of the product says it does NOT come with suction cups. You will have to purchase separately. I do item this is over priced for what it is. However I was in a bind and needed something quickly and this listing is the closest thing to what I needed.That being said I purchased this to keep my male and female axolotl separated in their 55gal tank. I had thought they were both male, well jokes on me when I found eggs in their tank. So far the separator seems to be doing a fair job at keeping them apart and I see no issues with the glass. Will update if any issues arise.

When placing an order I read the previous reviews and questions to make sure I am getting what I pay for.1) this will not work for small fish. I read a question where someone was asking if this will work for guppies and it said yes, that the holes are now smaller. - WRONG they slide right through.2) although this said it would fit a 10 gallon tank, it does not. The cut is so exact that I cannot turn the divider/plexiglass to actually sit perpendicular the the tank walls.3) I am assuming that it is sturdy enough but I wouldn’t know because I cannot get the divider in all the way.Since my fish can clear swim through the holes I will be returning.

The picture shows 4 brackets with 8 cups. I only received 2 brackets with 4 cups. The brackets are white, not clear. It’s really ugly in my aquarium, but I needed something now. I wouldn’t get this for a breeder tank as the holes are large and babies could go through. It’s a bit tall for my aquarium with an underground filter and gravel. I just flipped it to fit at an angle and it will work for what I need. I’ll modify it later after my fish grows a tail back and can go back with the others, or I get anther aquarium setup.

I tried other dividers and this one is superior. Please note that it is NOT see-through and instead is cloudy. I like that so I can keep the betta separate from the mollies for a visibly appealing tank. The holes are a bit smaller than a dime. The suction cups will need to be cleaned but I like the white color despite of that.

I bought this to fit in my 10 gallon tank. It arrived in great shape (with suction cups) and would of been a perfect fit...EXCEPT the holes were 8mm (approx. 0.315 inches) instead of the usual 5 mm (0.197 inches) most acrylic dividers have. Doesn't seem like a huge difference but with fish, it sure is. Very disappointed since my tank is just a little short and does not fit most of the dividers listed for 10 gallon tanks. I will be returning it.This would probably work great if you have NON-NARROW bodied fish. It would of been fine if I was separating dwarf gourami fish but I was trying to separate a dwarf gourami and a betta from my weirdo betta (who HATES the gourami but ignores the other betta) and while he wouldn't fit through the holes, he most certainly would get stuck going after the gourami (who is a little clueless that the betta hates him and is buds with the other betta).I saw an answer from the seller stating the holes were now smaller, so maybe I just got old stock. I still have my old divider (just does not fit well - was looking to fix that) so my fish are fine. (And if anyone is concerned with the tank being too small - none of the fully-grown fish are over 2 inches in length, so there is no over-crowding and they are quite happy with their tank, I just wanted a better sized divider.)

this worked well when used in my tank to keep my fish divided. They were very happy in there after and it stayed in place.
