First of all, big thanks to KeenShrimp & Baccus: A thread opened by KeenShrimp, and a reply Baccus did here did ring a bell to me
I said to myself: well, there's a nice estuary not so far, with a place with brackish to almost fresh water. Might be worth it just keeping an eye.
After day work, drove wifey at home quickly, jumped in my car, and run to the place.
And Bingo!!!
21 Nerites in 15 minutes I didn't even suspect I can find these horn nerite in my Country, never heard of them in any book. You can't imagine how happy I was when I saw a yellow dot on the immersed rock, put the all arm and shoulder inside water... and felt the horns under my fingers!!! I could not believe my eyes Then I found a second, and another, and another...
Sun was dimming, and I didn't feel confident in this place where deep water is very close from the shore and where the bull shark is sometimes cruising, so after the 21st nerite, I thought it would be more wise to come back later... I know what I will do this week-end
There are 2 kinds: 1 with horns, almost clear, one without, almost dark
I ran back home and acclimated them during 3 hours, and drop them in their tanks.
My favorite:
It's a true fact that these guys are trully unbelievable algae killers:
1 hour after being installed on this rock covered with algae- the rock is the size of a big egg-
2 hours after
less 1/2 hour cleanng on an anubias leaf
Gees, they made my day ^^)
