I have my tank set up with colored pebbles (bought at Petcetra) and now have been told they are not good. I put in a tray and 2 mini pots, I believe they are terra cotta and got them from a craft store. The tray is for the food and the pots are for the ADF to hide in. Also have been told they are not good and to remove them. I feed them frozen bloodworms, how much should I being giving them ? They are small, maybe an inch and I have two white clouds and one neon tetra, so really there is no competion for the bloodworms. Appreciate all opinons and advice. Thanks
