Regarding Ramshorns.....

[James0816]

Will they interbreed between species? I currently have reds in one tank and blue's in another. If they don't/won't mix, then I'd like to move the blues over to the other tank.

Blues and reds are not different species just different color strains so yes they will interbreed.

:iagree:

k...thx...don't want to mix and match.

Correct me if I am wrong, but aren't ramshorns assexual? So for one snail to breed it would not need to breed with a male or a female, such as a brown ramshorns can lay eggs by itself.

Rather than a male brown breeding with a female red ramshorn in order to lay eggs?

This is what I was thinking as well which is why I inquired.

I am not for sure here I would think that even though they can reproduce asexually bringing in a different color strain would still possibly affect the coloration. Maybe Jinkzy will stop by and settle this once and for all :grinyes:

I had to dug through my references to confirm my thoughts. Here for ramshorns..

Ramshorns are hermaphroditic and once two mate, sperm is swapped and both can go off and lay their own clutches of eggs. It has been reported that an egg clutch kept at 72F will hatch in only 9 days. Higher temperatures will increase metabolism and will cause the clutch to hatch more quickly.

Another for the Lymnaea stagnalis which may be applicable to the rest of the hermaphrodites. You knew snails can be complicated, of course?erv:

These snails breed readily laying egg sacs around just like the bladder snails (Physas sp.) They seem to use a seminal product to manipulate their partner and mate in the male role when enough seminal fluid is available in the prostate gland. Receipt of semen not only initiates egg laying in virgin animals, but also feminizes the mating partner later in life. This increases in the female function have been shown to go at the expense of growth and seminal fluid production of the sperm recipient. Although in Helix, and probably also Lymnaea, the sperm donor benefits from the induced changes through increased fertilization success, the sperm recipient may experience injury, imposed reallocation of resources, and altered sperm storage. These findings support the existence of sexual conflict in simultaneously hermaphroditic snails, and its importance for the evolution of mating behaviors and reproductive morphologies is discussed.

Ah ty for clearing that up Lupin :bowing:
