I asked this question previouslly and I gotta go back in and select the best answer so forgive my tardiness. I have a Betta in a Vase. A square vase. It is just shy of 3 gallons, I have a mini aquarium heater for up to 3 gallon tanks, a small filter and 2 tiny air stones with a pinched line so only a few bubbles get out for the betta’s comfort. I have small decorative rocks filled with brown gravel. 3 plant bulbs waiting to sprout and a Blue L.E.D. Light submerged for a night light. In the tank is a single Beta fish, 3 fancy guppies and a pleco algea eater (very very small right now) I plan to remove once he gets much bigger and replace with another tiny one. and 5 ghost shrimp. the water is 80 degrees constantly. Now that all being said here is my question. The plant i have growing outta the top of the vase is a Devils IVY. its only been 2 days since I put the new betta in and the new fish were added today. The betta though seems non active. it will swim though not much, the other betta i had to replace (I’ll explan why) was very active until it died. It mostly sorta hovers above the bottoms, or goes and lays down in the Plants roots, it doenst seem to be diseased, or sick at all, i add a little bit of aquarium salt every day, and the water is extremely clear.. I wasnt able to find anything online stating whether or not Devils Ivy is toxic to fish. That being said this set up doesnt involve the Betta eating any roots, I supply it with tropical flakes and blood worms. And soon after i buy a single female buppy live fry whenever she produces. There is also plenty of breathing room at the surface. Now as to the the first betta fish. The first heater i had malfunctioned. it was supposed to used for 3-15 gallon tanks with an automatic shut off. Well it didnt shut off, I basically came home to Fish soup and hard to see through water if. you get the idea.
Is this plant harmful to fish (devils Ivy) ??? I dont want aswers that include, well it is toxic to people dogs cats, etc etc. because queens anns lace is a plant (the original carrot) has toxic leaves and can be used for abortions however the root is perfectly safe to eat ( carrot). So if anyone knows whether I can or should contine to use this plant in this set up please let me know. Thank you in advance
