Thanks Jen!
Tanks are in our laundry/mud room. This spot works out great in terms of tank maintenance. A few feet to the left is utility sink built into the counter top and to the right is a door that leads a few steps down to the back yard. It's a busy spot as far as traffic goes, but not super busy.
For sure given the lack of tank space I keep little/no decor in these tanks and even when I do, it gets shoved to where ever the fish want it.
The pink light to the left on the lower tank is a cheapy LED "plant" light. It's shaped like a mini flood lamp style bulb. It's 5 watts, or so it said on the box. I've had it between 1-2yrs, going 8hrs/day. I did have some java fern in with the goldies, but it got too beaten and battered in there from them sifting through it. They'd avoid the plant itself like kids with veggies, but would happily root out any food that fell in it.
Even with that hot water baseboard heat, the lower tank stays a few degrees lower than ambient, so it can run anywhere from 60F in the winter to 80F in the summer.
The pothos plant in the top tank I started in one of those breeder boxes that hangs off the back of the tank like a HOB filter. Marina brand IIRC. It's got a bubbler tube you tube to an air pump, that supplies water to it and it trickles back into the tank.
Also have some pothos in the blue basket you can see in the lower tank. It's mostly flopped behind the tank.
The double stand is rated to hold two 75/90/120g tanks, but I couldn't imagine twin 90s or 120s on there. The top 75g is hard to reach into as is it's so high up.
