thanks guys for the kind words! these babies are monsters in training....i plan on keeping all of them and getting a bigger tank for them later or even sooner......i was thinking of a 10'x3'x3'.........hope thats good enough for the araipima what do you guys think?
C, buddy of mine kept a arapaima in his 10ft. long, 4ft. wide tank. Got it to about 2ft. and SOLD it! They are very strong fish. SCARY!! capable of breaking thru the tank... Be sure your tank will be very thick. preferably plexi. GL!!
