Aquator in Hele sold me the RTBS and 3 corys as my first fish and Pets at home sold me the Gibbi and algae eaters at same time.
Not sure exact dimensions of 5ft tank as dont have a tape to hand but its about 5ft long and id say 10 inches wide/deep and hmmmm 16 inches tall perhaps, its pretty big. Just dont have any money for the filter right now, did have one,an eheim powerball but it broke after one day of cycling in my hexagon tank, really want to use the big tank though, got big plans for it lol
where are you then if your local too me?
Aquator are normally pretty good, some of the best kept tanks in the area, Im surprised they didnt ask about tanks for the RTB although anyone can have an off day, they are normally pretty well clued up in there.
You dont need a big filter for a tank that size, probably 60"x15"x12"a little internal power one would do the job. Styles do some cheapy kit although you get what you pay for. I reckon you could probably get a adequate filter for £20, Might be worth checkin ebay as well. Or just save your money for a couple of weeks, I think styles do a tetratec one that would run that size tank nicely for £25.
Pets at home I doubt the staff had any idea at all that gibbiceps get big or that they cared.
Im in Torquay as well hence the "TQ" in the user name.
