A few months ago I decided to move my two year old betta to a 20long and fill it half way so he would have an easier time getting to the top. I added some plants and thought hey what a neat idea I have found ha ha ha, upon further research I found out what I was doing was called a Riparium and someone, many someones had already thought of it!!
Anyways here is my tank and I have questions on plants and toxicity to fish further down.
From outside to inside I have Umbrella sedge, coleus, spathiphyllum, ivy, dracena colora
I have kept under water simple with crypts and java fern and marimo moss.
This tank has 0 nitrates. I liked the idea so much that I decided to add some land plant roots into my main 35g community tank in the hopes of having to do less water changes.
This tank I added curly bamboo (dracena), pothos, philodendron and sweet potato vine.
There seems to be some question on another forum I am on whether these plant roots would be toxic to my fish. I would greatly love some imput on someone knowledgeable about plants. Specifically I have been told I shouldn't be using the philodendron or the curly bamboo though my initial research does not show they are toxic to fish.
The list of plants I am working from are as follows, though I know there are many more that could potentially be used:
Herbs, including mint, basil, oregano, lavender, rosemary, and sage
Ivy (any type)
Sweet potato vine
