Self Sustaining Food Options
Good evening everybody! I wanted to get some peoples opinions on some additional self-sustaining food sources for my puffer tank.
I currently have amassed a small colony of: Malaysian Trumpet Snails and also recently introduced Pond Snails and some Ramshorns as well (though I have a feeling they ate most of the Pond/Ramshorns before they could reproduce).
In addition to the snails I have quite a colony of blackworms...which was a shock to me as I introduced them nearly 6 months ago! A month or 2 ago I was studying my tank very closely and thought I saw a couple worms but thought no way. Proceeded to shine a flashlight at them and sure enough they shot right back into the gravel! I was so astonished to see them; I only expected them to live a couple weeks (if they weren't dinner) and now they are multiplying.
So any other ideas for self-sustaining food sources? Not even necessarily for the puffers; they're very happy, I just find it very fascinating and cool to keep this up, while adding to my ecosystem! Thanks for any help!
