Hey everybody, I'd like to start by saying this is my first time on the site, it's nice to find a group of like minded people searching for more practical and safe means of living.
So I just started my first aquaponics system on a small scale. I'm currently using a 275 Gallon IBC container in a flood and drain system. Everything seems to be going well. I'd like to use tilapia in the system soon but it's stocked with goldfish at the moment because they were a cheaper alternative.
So my question to you guys is, what can I do to keep my goldfish happy? I know it seems like a trivial question but I've never owned goldfish and I want to make the best environment possible for them.
What types of submerged plants do they like and feed on?
Are goldfish omnivores? If so will they eat meal worms?
Is it okay to use pea gravel in the bottom of my fish tank?
Do goldfish like having places to hide?
I've already covered the necessities for their survival, the tank is getting plenty of aeration, the water temp. stays between 60-80F, I'm feeding them twice a day without overfeeding, plenty of sunlight.
If possible could you guys post some pictures of your goldfish tanks it would be much appreciated, thanks for any help and advice
