I got a small 1.5 gallon tank, wanted fish but could not have big aquariums in my apartment, checked with landlord, and showed before got said was ok. It did not come with heater, most seen too big, or no way to really control temp. saw this one and has display, and can set to temp want. Seems to be working and keeps around and shows temp of tank, one big draw back is the cord is not very long needed to add extension to reach the USB charging block pluged in.
