I used to be mad into the Fish hobby but then I've slowly weened off it now because I just don't have the time to take care of them. I had MTS (Multi-Tank Syndrom)... and was at one point running like 8+ tanks, water changes alone would take up a huge chunk of my day (like 5+ hours) ... but I've cut down to just 1 small 15g tank now until I have more time in the future ... these are pictures of my old tanks that I had a couple years back ...
My Red Belly Piranha's, they are actually pretty shy, but when they attack or are frightened, wow damn they move fast ... I would NOT want my finger in there ... lol ... it's fun watching them rip pieces of meat apart though ... messy to clean up after ...
My Green-Spotted puffers, 2 of them, stalking a giant marbled cray!... epic battle time!... haha I'm just kidding, sadly my big mama crayfish passed away after I've had it for 3 years... she was responsible for having many many little cray babies so I could feed my puffers, so on this day she would be my 2 little GSP's buffet.
Also kept a few Saimese Fighting Fish, they are calm and beautiful.
The baby cray's playing tug of war with a dead Neon Tetra... such is the circle of life!
2 older crays chillin' in their holes.
