B) I don’t know much about that plants, if they don’t have poisoning substances which they give into the water … :whistle: perhaps they could catch mosquitos when the Paros don’t eat all the mosquito larvaes and puppies?
But I think, Paros just need some swimming plants on the water surface for shelter and some java moss as hiding place for offspring…
Utricularia (not: Ultricularia) gibba is safe and fine; all bigger Utricularias are not. I have often used U. gibba in breeding tanks without any problem. I never would do so with its bigger relatives.
That’s good! Thankx 🙂 U. gibba was the main species I had in mind, as I was not sure whether the other species has bladders large enough to threaten Paro fry. On a side note…if I could find a sufficiently inert/acidic substrate that doesn’t alter the TDS much, could I grow terrestrial bladderworts emersed in a paro tank?
I also have U. gibba in all of my tanks. It seems to establish by itself and was not introduced on purpose.
When I visited Kuantan all the possible Parosphromenus habitats were coverd with a large growing and yellow flowering Utricularia sp.. I took some, but it did not grow as expected. I don´t think any of the usual aquatic Utricularia do harm fishes.
