Hey everyone, I'm new to the hobby and just started my second tank - hadn't completed my cycle on the first and have to start over. I'm running a 25L fluval chi with heater set to 26c stocked with 5 male guppies and 1 male Endler. They seem to be having a good time, waters clean and I've run a water test for ammonia which has stayed at an easy 0 so no issues no far! Being the sceptic I am I've constantly been wondering if I'm overstocked - the fish store we got ours from tested the water and advised we'd be fine with 6 guppies providing we trusted our filter (which we do) but there's a lot of contradicting opinions out there and I've seen some people say we should only stock with about 3 guppies for my size tank. I've got 2 live plants in there and 7 Marino moss balls as well as various plastic decorations including a 7" tall stone for them to swim around. No aggression shown I don't think just some playful chasing so far.
