Tetra 3 Gallon Half Moon Aquarium with LED Bubbler

I'm writing this from the perspective of someone who has successfully kept aquariums for over fifty years. The tank itself is a nice size and shape and perfect for a batch of guppy fry, a betta, or other small tropical fish. Three gallons is not too small; with a fully cycled filter you could easily keep half a dozen mature guppies in there. As others have stated, the lid does not fit perfectly once the tank is filled with water. This is poor engineering. My workaround was to take three strips of white masking tape and fasten them on the back edge of the lid and the back of the tank to make 'hinges.' This makes it a lot easier to open and close the tank lid without dropping it in the water, and it is not super obvious from the front side. Another common complaint about the tank is the difficulty of getting the bubble wand to lie flat on the bottom of the tank. There is a really good workaround for this. Please look up "Aquarium Suction Cups, for Fish Tank Airline Tubing" here on Amazon. Lots of sellers have these, this is just an example. I used several of these suction cups under the gravel, placing the first one near the connection between the airline and the bubble wand. I put both the air line and the (very thin, seems like inadequate insulation) electrical wire in these suction clips, then covered it with gravel. Works perfectly, and no problems with the bubble wand ever getting loose. Unfortunately, the bubble wand lights, while pretty, are not bright enough to illuminate the tank, while the bubble curtain set on full blast creates a current which is much too strong for small fish to handle on a 24-hour basis. Be aware that the constantly swirling current of this bubble wand on the full setting may stress your fish to the point of death! For my guppy fry, I turned the bubbles down so only a single section of the wand is working. And if you want the tank to be properly illuminated, you will have to go looking for an appropriate light. Although I enjoy the beauty of this tank, none of my improvisations should be necessary. The suction clips should be included in the kit, and the tank walls should be stiff enough to not bend when it is filled. The lid definitely should have had hinges to begin with, and there is a lot of extra bother and ugliness with the two air lines that drive this tank. I can easily imagine how a beginner could quickly be frustrated by this 'starter kit.' There is one really good accessory included in this kit: the novel air-driven internal filter. I've never seen one of these before. While some here think it is too weak, the slow flow is absolute perfection for a weak-swimming betta or for small fry, and there are no electrical parts to break. I LOVE this filter! So that's about it. Basically, this kit was a great concept, but falters in execution. I don't regret buying it, but a true beginner will probably feel otherwise.
