uumm.... i honestly don't know. x: i don't know what kind my medicated food is. for internal parasites, use regular pellets, but soak them in fresh garlic juice. that's supposed to help ALOT with internal parasites. :3 hope your fishy feels better! two of my girls are sick. D:
I agree with everything you told abby, you don't sound stuck up to me. You just sound frustrated, which is how I usually sound when talking to people about keeping outside animals or breeding mutts/pitbulls.
Idk Much about mollies, but why not put them* in that empty 20 and the plants in the ten?
Id say putting them in the tank by the window is fine, keep watch for algae! Even if you get it, its not bad. Maybe get a couple snails? That way the tank gets ammonia and they get noms? Also, after a water change in the molly tank, put some of that water with the plants so the plants get an ammonia snack! Do a water change every few days (partial) to cut down on algae and replenish nutrients. Some plants need a filter for oxygenation, so keep that in mind!
As for keeping them with the fish, you can google how they interact with reach kind of plant. Also try having a small one of a plant with them and see what they do, like a test.
B: <3 remember to fertilize while in the tank by the window, so they stay happies!
They really don't LIKE company. :D Yeah, he's happy. I guess I've had him for about a year now. He's cute. Here's a good site with great info! This is what I used to research and set him up: www dot dwarfpuffers dot com
