Very nice small aquarium. Great because dimmable LED lighting. With blue night / evening light. Also mixture of both light colors possible. This a rather yellowish or cooler light. However, I recommend the removal of the box (secured with two thin silicone strips on the inside wall.) -I Have the very good job with a sharp knife. This should be done before filling the aquarium. The box is quite large and the filter can also be operated alone. It has its own suction cups for mounting. Now more space is essential in the aquarium. The box should lt. Serve manufacturers to intergrieren a heater in this. In my apartment, since all has a constant temperature, I need at least no heater. The 4 or 5 Mini fish and few plants are also without additional heating in fine fettle. (Incidentally, was a hint of professional seller) On the subject of loud filter. True and not true. The filter is very quiet - except there is still air in the enclosure. Can just turn around under water and the air to escape. After that, the filter is actually no longer perceptible. After a week, a few unproblematic fish and plants inserting and that was it. In the small amount of water the last note should be really taken seriously. Conclusion: Very attractive Mini Aquarium and great little livelier eye-catcher.
