Afternoon fellow Aquarist .. My first time on a fish forum .. after keeping fish for around 15 years .. Started off with gold fish in a little 2 foot .. and some what 10 years ago i purchased a 3ft when i started stocking warm water fish .. mainly kept tinfoil barbs, silver dollars, and still have my pair of Red Tail Cigar Sharks .. which are now 5 years old, as well as a silver dollar that i got with them .. About 5 months back i came across an add for a 4ft with internal " sump ", made an offer .. and collected it a few days later ... the 4 foot now stocks my Pair Cigar Sharks .. 1 Silver Dollar .. 2 Spotted Dollars .. 1 Green Severum .. 1 Paradise Fish .. 1 Pleco .. and because i had the bigger tank now, i could finally get one of my Favourite All Time Fish ... Silver Arowana ! i have always loved their shape, and majestic way of cruising the water .. i got him at 3-4" long, rather skinny on the 25th of March 2017 .. He now is around 9-10" long and definitely rules the tank .. he has even grown bigger than the Cigar Sharks .. I will be collecting a 5ft soon, and will document the setup of that .. looking forward to being on TASA and sharing this hobby with all of you!
