I thought I'd mention again the tank mates with these rabbit snails. There are two mated angelfish, 8 bronze cories, a bristlenose pleco, hundreds of Malaysian Trumpet snails, dozens of ramshorns, and then all the rabbit snails. The fish require different water parameters from the snails. I would not recommend keeping them together, and as soon as I can, I plan on a Sulawesi tank (though that might not happen for some time). For now I keep cuttlebone in the tank, provide vegetables (that the pleco and cories also partake in eating) and am experimenting with different supplements and foods. Yesterday i made an attempt at a supplement that contained calcium pills, powdered cuttlebone, algae wafer, fish flakes, and honey. It seemed messy, dissolving even though i'd frozen it, but it was gone in a few hours. I did not see who ate it, so it could have been fish too.
Last night Izzy (thekoimaiden) linked me This
article, which had a little bit of info about rabbit snails. One tidbit was how to sex them!!! "The snails are sex specific, females having a grooved channel down one side of the their shell and along their foot in order to deliver singular young, which are covered in a protein sac that dissolves at birth." (from the article). You wouldn't believe how excited I am about that information- in fact I noticed said channel on my snails. I've tried to get a better look at my group, and though most of them are being hidey-meanie faces (very scientific i know) I believe i have at least one male white spot, one female white spot, and at least two female yellows.
So as promised, i've got a couple of pictures!
These first pics are one of the baby snails that have grown up in my tank. She (i believe she's female) is almost a year old.
Here is a shot of the difference in the snail shells. The snail on the right is one of the yellows I received in this order, and the one on the left is a white spot from this same order. Notice the different textures on the shells (as best you can- i apologize, these are all phone pictures!)
the yellow female (and all the other yellow babies from my original female) has a very smooth shell. I believe this is due to my soft, acidic water. I try to supplement what I can, though I hope I can devote a proper tank to these snails soon.
the shell of a yellow from this order; probably reared in a harder water tank.
TODAY i tested the water in my 29 gallon.
High range pH: less than 7.4
NitrIte: more than 0ppm but less than .25ppm
This seemed very strange. In the past I've tested my water and my pH had been around 7.4 and high range around 7.6. I did a large, 15 gallon water change, rinsed my filter, then re-tested around an hour later.
High Range pH: less than 7.4
Something about my tap must have changed recently. I even remember writing down that pH was 7.4 and HR pH was 7.6, and so called it 7.5 in my mind. I know snails do better in higher pH Would you guys try to up your pH or just leave it be? I add cuttlebone and occasionally other supplements to help my snails keep their shells in shape.
Also, I went ahead and measured the snails closest to the glass of the tank. The white spot i believe is male (and just called male 1 in my mind) is about 2 inches long. One white spot whom i believe is female (female 1) is about 1 3/4 inches long. There are two more white spots, and one is definitely larger than male 1. I also measured the white spot babies, and they range in size from .5cm to 1cm.
Also, an interesting note from what I've observed of my snails in the last year: It seems the young snails and the male snails are more active than adult females, especially in the day or two after the adult female gives birth/lays her egg.
