Hi guys ive seen two congicus for sale at around 10 to12" for £50 each but im a bit worried that they will get too big,i know tthe sticky says 39" but whats a realistic size in a home aquarium?
mmm, thats the size when I got mine, I put them in a 200g tank at this moment,
I dunno if its gonna go that big in a home tank, but your 180g should be just fine.
