Snails - Brigesi, Red Ramshorns, FW Nerites
Hi. I have many questions on the above species, so please bear with
me. I've finally got Pomacea bridgesi established in my tank thanks to a group member who sent me a few. They are great tank cleaners, I have to admit, I think they do more work than any otto or SAE as they are going 24/7 and seem to always be hungry. Unfortunately, I seem to have all males (I could be wrong, as I only have 3 to examine), and none of them seem to be changing sex at the moment. Logically, my question is does anyone have any extra brigesi snails (any variiety - I am not picky) they need a _good_ home for? I can pay for shipping and extra if you want payment. The tank in question is a 72g, and there is also a 55g and 20g if they reproduce (I don't cull.). They will be going to a good and loving home with no predators and plenty of food. I've tried posting on applesnail.net, and waited a month, but no one seems to have any to sell. I don't wish to purchase them from a fish store as I used to work in one (and know the conditions snails & fish may suffer through in transit and in the tank itself). In addition, I prefer to know what I'm getting is what I asked for (not mislabeled...) and is healthy. If at all possible, I'd like the larger ones as their shells seem to not crack during shipping (all 3 of mine have completely cracked shells - but are doing fine anyway). This is a long shot, but does anyone know of a source of _freshwater_ nerite (family Neritidae) snails (usually associated with sal****er or brackish tanks), but apparantly there are FW species that have the same algae eating preference. Doing research, I have found that they list these species as FW: Theodoxus , Clypeola, Septaria. They all inhabit tropical FW streams. Other pages reference other (invading into FW from SW) species: Neritilia, Neritodryas, Fluvionerita, Clypeolum. They are apparently quite adaptable if they can transition from a SW or brackish environment to a FW stream. Are there any online sources or does anyone actually own any of the forementioned species? I am at a loss as to where to obtain them, as they seem quite perfect, and perhaps even better than the tradition plant snail (Brigesi), in color varities (bright colors!) and eating preferences. Also, a lot of people seem to swear that red ramshorns (Planorbis Corneus, I think), are good companions for a heavily planted tank. However, there is a lot of conflicting advice given about them. In researching them they appear to be omnivorous and will eat both rotting matter and soft plants, in addition to fish food). Some say they are bad for a planted tank and some say they love them in a planted tank. Opinions on why this is so? Is this a simple matter of making sure you _overfeed_ so that they are not tempted by soft vegetation and instead eat dead vegetation and leftover food? If this is the case, then I may be interested in obtaining enough to colonize my tank (if anyone has any to sell me, again I will pay for shipping and what you feel is reasonable). I am a prolific overfeeder (the MTS love me I think), so the red ramshorns may do good if providing enough food so they aren't tempted by living vegetation is the only concern. This is another long shot, but does anyone have any other species of MTS (Family Thiaridae, not the common variety as I already have a good colony of those)? I am not able make a positive identification on mine as to if they are granifera or tuberculta, but I am leaning to granifera based on the coloring and no apparent stripes. There are a host of other species out there that I would be interested in keeping for curiosity sake. Does anyone have any other species, or again, know of a source from where to obtain other Thiaridae? Thank you for any help as I know this is not the Snail newsgroup, but it seems most snail questions (as relating to plant ecology) are posted here. If it is horribly off-topic, I apologize. Thank you again, Allen |

Snails - Brigesi, Red Ramshorns, FW Nerites
Did some checking, and all three snails varieties in my tank appear to be
tuberculata. The two links below show the green/brown and the red mottled varieties. http://www.applesnail.net/content/ph...ides_tubercula ta.jpg http://www.microgravity-systems.com/...eckelschnecke0 1.jpg "Owen Graupman" wrote in message newsyXV9.55648$wQ1.46083@fe01... Allen, Can't help you with your other questions, but I may have some help for you on the Malaysian Trumpet Snails. I have three 'varieties' of MTS, though I cannot say for certain if they are of different species or just varying in color. I have been propagating them for some time now and consistently produce snails in these three varieties. The first variety of MTS produce long shells (a few about 2-3cm, but most around 1.5 cm) and have a unique coloration. The first two twists of the shell (counting from the opening at the larger end) are always striped green/brown and usually have algae growth. The remaining shell segments are always pure white without any algae. The second variety of MTS produce white shells and grow to about 2cm. They are frequently covered with filamentous algae even when algae is not noticeably present in the tank. These rarely seem to breed and seem to have softer shells...I've cracked a number of them just by picking them off the glass. These are definitly the rarest of the MTS in my tanks. Maybe they are just a freak 'albino' MTS. The third variety of MTS produce a white shell speckled with red mottling all over. I have never seen one grow past about 1cm. These are also, by far, the most common MTS in my tanks. My wife and I are building a home right now, including a custom fish 'experimentation and propagation' room. I was planning on including several breeding tanks just for these snails so that I can try to identify if they are indeed different species, and also study if any of them prove to be better or worse at cleanup tasks. I'd be happy to send samples of the green/brown and red/white varieties (which breed commonly) if you're willing to cover the shipping costs. I'm down to only four of the white variety at last count and don't want to risk this line dying out in my tanks. -Owen Graupman Remove the noreply from my email address to respond to me directly.

Snails - Brigesi, Red Ramshorns, FW Nerites
Hi,
Several people have emailed me regarding these species of snails and I thought I would summarize and post so everyone can know this information. I have found a source of freshwater Nerite snails if anyone is interested just email me, and I'll send you the link. She is a very friendly person. It appears there are real differences between red ramshorns and red ramshorns. There are ramshorns that are red in color and then there are true european red ramshorns that are a different species all together that do not eat plants (as far as we know). Much of the red ramshorns sold in the aquatic trade are not this European species, thus earning their mislabeled rap. Overall, if you have the true species, I'd say you have a good snail. No one seemed to have any extra brigesi snails, which I thought was strange. They are quite prolific breeders, but I will purcahse adult specimins instead of taking extras off the hands of hobbyists. When it comes to MTS and there are two common species in the hobby: granifera and tubercutula. Granifera (the species I have) are a plain dark brown and top out at a max size of 1cm, although that is somewhat rare (3/4 of a cm being most common). The other species, tubercutula, is apparently quite diverse in it's markings and size. It can grow anywhere from 2-3 cm (depending on variety) and its striping pattern is as diverse as brigesi snails coloration it appears, with green and red being the most prominent as stripe colors. Their shells are lighter colored than granifera. They apparently have a great deal more genetic variability (mutants and albinos were mentioned) than granifera, as I have never seen a granifera that did not look dark brown and showed any qualities that would make it different. The varieties do indeed seem to be varieties and not seperate species as it appears they interbreed freely. This is second-hand as I do not own this species, but based on research and what people have told me all of the above seems to be a good summary. Best of luck to plant AND snail lovers, Allen |
