Just remember, the 1000L will only last for so long (Probably 2-3 years.) So remember to not forget that he will grow 5 feet or so.darkcurves;3509024; said:Well, i finally got my RTC. He's not 2in, actually more than 3in. Seems to be ok with Pacus but he just does nothing . I guess that is their natural behaviour. I already planning to get atleast 1000L aquarium now.
