I find this question quite narrow. You cannot provide nutrients to the fish without giving them various foods which includes live foods but this cannot be done in a 1.5 liters soda bottle. We often recommend you vary the food menu as fish can obtain different vitamins in several foods provided.

Gravel vacuuming otherwise only the lazy person would ever think plecos can eat crap. Aquaria is a closed ecosystem and so is the pond so we use filtration and vacuuming to eliminate the crap.
• How will your aquatic animals get rid of their waste? (hint: this will require a decomposer)
| Tap water treated with dechlorinator is recommended. Pond water has a lot of harmful microorganisms and is not advisable for use.
• Water: fresh tap, old tap, distilled, or pond water? |
• Gravel, sand, or a mix?
Your teacher is so wrong. This will happen only in the pond, not a 1.5 liter soda bottle. We'd never recommend any fish for that size of container.
It seems like we're supposed to create a food chain in there, so that they get their nutrients and food naturally rather than being fed. So, any advice on any of these topics?
