I think it's 4ft will have to check when I'm back at home, comes with plenty of fish, plecs clown loaches mollies loads more, one of the plecs is pretty big and could probably do with being put in a bigger tank. Needs nothing but a 50/60% water change. Comes with 2 filters heater bubble maker ect. Fish tank in mint condition but As I said it could do with a water change and a quick clean. I have all the stuff needed. Any questions feel free to ask. Comes with stones in bottom of tank, plenty of accessories and ornaments ect, box full of cleaning stuff i.e sponges especially for fish tanks. All water treatment stuff needed. Brand new sponges in the filter. Basically new heater. Water transfer pump, large bucket for transferring fish with. Plenty more. Well worth the asking price as the tank cost more than what I'm asking new, without the stand. All included. Please text as may be at work ect. Thanks.
