Do trumpet snails get bigger?

Answer 1

Yes but they dont grow too much. And you probably won't see them grow. They grow too about 1-2 inches. They breed very easily and your tank will soon be infested with them. They pretty much just eat fish crap. Which is good for the tank.Trumpet snails are shaped like a cornucopia. Some may be egg-layers who live in the substrate. Malaysian trumpet snails, or Melanoides tuberculata (another source says the Latin name is Melanoides tubercularia), are a sexual, live-bearing snail. The males are noticeably larger than the females. They are often said to be good because they move the substrate around and aerate it. They spend the day in the substrate and come out at night to feed on leftover food and plant debris. Trumpet snails will not usually harm live plants. They can reproduce quickly sometimes. These are good snails for aquariums that need substrate to be turned over. Most stay under an inch in length. One source says they need to be at 64 degrees F or higher.
Good luck finding them though! None of my local aquarium stores sell them nor have I found a mail order company. Most aquarists who use them in planted tanks got them with their plants as they often hitch a ride with plant shipments. My local store only has pond snails and tiny ramshorn snails that hitch rides. Jane was nice enough to alert me to one internet source for Malaysian trumpet snails at Three Guys Aquatics. Chris also told me that you can sometimes get trumpet snails if the store collects them as "pests" for discarding. If you encounter nice people they can give you some free since they just throw them out anyway. My local store will NOT sell you something that they do not have officially for sale with a price because they do not want to lose any money even though they are not even selling the "pests!" If I wanted some, I would have to find a tank infested with them and buy some plants from that tank to get them "accidently."
"I stumbled upon your article on trumpet snails. I got some 'accidently' with live plants about two years ago. In about two months they infested the tank. I found clown loaches like to eat them, but they leave enough adults to sustain egg laying. If you do get a few, lower the light intensity (3-4 weeks should do) and increase the temperature to 74-78 degrees. They'll breed like mad. Now I can find a dozen or more buried in the gravel at any time, but rarely more than 2 visibly searching the tank (even at night). It seems to be effective for feeding a clown loach, but won't make much of a dent in algae if a clown loach is present. I have been trying to seed my other tank with trumpet snails for several months now, but I won't raise the temperature past 72 due to breeding fish in this tank. The snails don't seem to breed in these conditions and die of old age. I have found, between sixteen different aquarium set-ups that got these snails at the same time that I did, that they cannot unbury themselves in small or fine gravel if there is a mechanical undergravel filter present. They aerate best with gravel over 1/4". They also do well in fish bowls, but I don't know why. The largest one I have seen was over 2", but it would no longer lay eggs at this size and eventually died."
