Anyone have this tank? Tetra Crescent 3 gal.

[Seki]

I am having a lot of trouble with my new betta and I am starting to wonder if it might be that there is something nasty in his tank. I am highly considering taking it apart and bleaching the crap out of it, but of course my guy needs somewhere to live if I do. So today I purchased a Tetra Crescent 3 gallon tank at Meijer. I had planned on getting a 5 gallon TopFin kit from Petsmart like before, but a variety of reasons prevented me from getting to Petsmart.

Anyway... I had not seen this tank before, and I was curious if anyone knows anything about the filter being good or bad? Also I am curious about the LED lights since I have only ever had incandescent lights for my tanks. I am shocked at the online price... I got this tank for about $40, nowhere near the online price. o_O

This is the exact kit I got.

I might or might not turn this into a tetra tank. Thoughts?
