Hi, I'm into fish, Currently an 100 gal fresh water community tank. I also kept saltwater fish for about 5 years. I've kept fish most of my adult life, and my dad kept them as well. So yes.
Ive had numerous tanks and set ups over the years, since I was about 12ish when my uncle gave me his old tank set up for my bedroom!
Ive had community tanks, with your guppies, neons, sharks, barbs, plecs etc etc Had a tank with Chichlids only in and also a pond with goldfish in
My prized possession was a 5 foot x 2 foot x 2 foot tank which used to have red belly piranhas in it (great teenage entertainment), after them it also housed 3 oscars which grew HUGE.... and would come to the side of the tank for feeding and stroking!!!!
Only got a 4 foot x 2 foot tank now in my own house, this did have fish in till a while back but it now houses a Bearded Dragon
