I hear different requirements for these fish all the time, some say they grow between 4-6 inches and that they can live in small aquariums others say they will outgrow a small tank and need something around 20+ gallons.
So basically I visited family tonight and my younger cousin had a bristlenose pleco in a smaller tank, its the same size as mine 6.5 UK gallons which is around 8 gallons US I think, she also had a male betta (I got her in to them
) the LFS told her it was fine to have it in a tank this size but im not so sure, surely it will outgrow the tank sooner or later right? the tank is 18 inches long and the pleco is around 2.5 inches at the moment, Any advice? I have checked the profile on here but I didn't see anything about tank sizes, maybe I missed it.
