fish tanks are a lot of work for sure. salt being a ton of work. i had 5 fresh water tanks set up at one time, weekly vacuuming sucked for sure. i had the kids 10 gal, a 30 a 35, a 55, and a 125 all going at the same time.
my brother had a 125 high salt tank, that cost a arm and a leg to keep up, lots of testing, fish cost to much as well. as well as live rock and all that other cool stuff we all want in a salt tank lol he had it for maybe 5 years and sold it all off.
just like i did, some of my fish lasted over 10 years, they also got sold. when you got angle fish that their fins hit the bottom of the tank and the top of the water line, (125 long 18 inches tall) body's 5 inches round, and you bought them when quarter sized, theres 10 years plus of good water and food.
then my brother went nuts, and dug a 3 foot deep pond in the back yard, and made a koi pond.
this is it empty for a cleaning.
the fish in a kiddie pool. these all started out small, and grew this big. lost a few due to lighting strike, blew out the lights and pump as well.
some fry fish, born in the pond. he took them indoors in a tank to let them grow more, then put them back in the pond when they were larger.
left side is a water fall, it stays on year round, makes for some nice ice shots.
dog on frozen pond lol
