I thought I would start a new thread regarding my venezuela pike friday will be 4 week that this fish was shipped to me instead of a dwarf regani . In those 4 week it has bulked up quite a bit length wyse maybe a couple mm I have it in a 300 lt 4ft tank now I know these get huge I saw some fully grown ones on you tube so a larger tank is needed in very near future. What I woluld like some advice on is tank size for a solo fish and tank size for one with tank mates I know with tank mate can be a mine field with these pikes advice needed.
