I feed them a mix of tetra cichlid logs, pellets, flakes and crisps 2 times a day and frozen flounder and shrimp like twice a week and feeder fish like once a month.
The homemade plants are made of fake plants from Michaels arts and crafts store which I cut to size and make sure to remove any wire core from and then hot glue them into bottle caps for anchors. I buy 2-3 plants at like $5-$6 a piece and can make 3-4 large plants or 5-8 med/small plants from each. If you figure 3 tall plants at a LFS
can cost $8-$12, it's not a ton of savings but every little bit helps.
