Up for sale are some pond gold fish/comets. Various sizes starting at $10 for 5 inch fish. Can bring to meeting Saturday or come pick one out in upper Marlboro.
Also have some winter hardy yellow lilies. $10 ea.
I've tried it with the pump on the return side and I couldn't get the lid to stop leaking.
It's risky enough with regular manufactured canister filters I wasn't gonna keep trying with 220 gallons at stake.
I can thin out the native gambusia in my pond if you want some.
I also have some Neocaridina mutts that i should be able to pull a couple dozen out of for ya.
Available any time after 5:00pm during the week. I'll probably be home this weekend too.
