My fish like it. It's fun to watch them scoot through. It's worth it Imo.If you want this under substrate then try to put this in before adding soil, sand or gravel otherwise you will make a god awful mess.Superglue the parts together because mine separated a couple of times.Be careful not to add small things nearby because they will go straight down and stay trapped because i do not want to attempt to disturb the substrate again just to fetch out some acorn shells.Functional and fun but fiddly and messy to put in under soil substrate so bear that in mind.

It looks great! Fasteners to connect it all seem pretty tight and sturdy. Make sure you gently wash it without any harmful chemicals of course. The rock I have on top isn’t very heavy so we will see if it can hold it!Big enough for some small/medium African cichlids to fit into.

The tunnel is made from thick plastic and the connectors are tight and secure. It also comes with instructions but with little common sense you can put it together. My corydoras love it. Highly recommend

I got this for my Kuhli loaches, but it seems that a lot of my fish like it. Even my Empire Gudgeons go in there and hang out. Some of my snails seem to like it in there too, though they don't stay in there all the time. It's really a nice little cave, and really the only aquarium friends who don't seem to care for it are my shrimp, who prefer to hang out in the guppy grass, or on the buce, I guess there is more delicious stuff growing on those for them to want to leave them. They really keep the algae gone, so even though I don't get to see them often, it's fine if they do that since they're helping to keep things clean, which on those plants, no one else seems to want to do. Hillstream loaches and snails keep the glass so clean that there is no algae to scrape.At any rate, if you have shy fish which prefer to hide away in dark places, a tunnel like this will be choice real estate. It is designed in such a way that you can put sand or gravel on top of it so that it doesn't uglyfy your aquascape at all. You can even glue an epiphyte to it if you want/need to, and it will support a fair amount of rock weight also if your design calls for it.The only drawback to it is that it is extremely hard to clean, so make sure not to drop any food down in there. You will eventually have to pull it out to clean it, but if you put some gravel or sand on the floor inside it, and if you have enough cleaner critters in your aquarium, it should be a long time until you need to pull it out for cleaning.Overall, I give it five stars, because the cleaning quibble isn't a big enough concern to keep it from being a great place for fish to hide, but still be visible. It is also sturdy and that has to be worth something these days.

Der Unterkiestunnel von Lifewithpets wirkt sehr robust und stabil gebaut.Das Plastik ist stabil, stinkt nicht und die Montage erfolgt intuitiv und einfach. Die Verarbeitung ist erstklassig, es passt exakt in die Ecke des Aquariums.Die in den Beschreibungen beschrieben Schwierigkeiten bezüglich des Zusammensteckens kann ich nicht teilen. Ja das Plastik ist einmal zusammengesteckt sehr fest verbunden, hierunter sollen ja aber nachher auch Tiere einen Lebensraum finden. Das Zusammenstecken erfolgt relativ einfach, mit geringem Kraftaufwand.Aktuell ist mein Aquarium noch nicht befüllt, sobald es eingebaut ist, werde ich sehen wie stabil der Tunnel ist. Ein Blickfang ist er auf alle Fälle!Der Versand erfolgte international aus den USA. Die Versandzeit war fast eine Woche kürzer wie angegeben. Lediglich mit der Sendungsverfolgung gab es Probleme. Versand wurde laut Amazon mit DPD. Hier kam bei der Sendungsverfolgung leider immer nur ein Fehlercode, das die Sendungsnummer nicht existiere. In Deutschland erfolgte die Lieferung dann mit Hermes, obwohl weiterhin DPD angegeben war. -- Trotz dessen war auch die Lieferung nicht zu bemängeln!

Easy to assemble. Appears to be 3D printed, prob why other reviews had issues connecting the pieces. The quality of mine was fine. I got this for my bottom feeders and they seem to like it. The tetras can't figure it out, so it's a nice little space for them to sleep.

I’m really glad we purchased this for our tank. It fits nicely in our 10 gallon tank, is sturdy and adds a a fun hiding place for our fish. I didn’t find any of the edges to be too sharp for our fish, it was easy to put together and it feels well made. My only minor complaint is that when I was fitting it into the tank one of the sides came undone (probably operator error) and snapping it back together was a tad difficult in the moment.So far the loaches, guppies, Cory cats, dwarf crayfish and tiny pleco have all dropped in. Highly recommend, especially if you have shy fish who tend to hide!
