Betta may have attacked new snail?
4 days ago I brought home a snail for my 10 gallon betta tank. The tank is heated, running an aquaclear filter, and is mixed live & silk plants. Weekly water changes and parameters are fine.
He’s my Betta’s first tank mate. I’m not sure what kind of snail he is, but he’s the larger one in this picture that I took at petco. The only snail I’ve owned in the past was a nerite who ended up living by himself. This was because my fish at the time ended up being too aggressive even just towards me so I didn’t want to chance it by adding the snail which I had already purchased and brought home.
This new snail had extremely long antennas when I brought him home 4 days ago, and naturally I was concerned about how my current betta would react to him after my last experience. I spent a few hours observing after adding the snail to the tank and my betta seemed completely unbothered. Didn’t flare or do much of anything really other than look at him and swim away. This morning however, I noticed that my snail’s antennas are considerably shorter. I’m assuming this was the fish’s doing. Now I’m baffled, because I still haven’t seen ANY signs of aggression from the fish towards the snail. Levi (my betta) actually started building bubble nests again shortly after adding the snail. The snail is moving around fine, and the only tank I could move him to is a 2.5 gallon Fluval spec with my sister’s female betta which has seemed sick lately, or in the process of dying from old age. Plus the snail poops A LOT - and I mean, A LOT, so I’m worried about how efficiently a tank that small could handle the amount of waste coming from the snail.
Before buying the snail, I read online that the bigger the snail, the less likely the chance that the betta will try to prey on it, so I decided to bring home the biggest snail that I could find at the time. Now I’m paying for it haha.
So my questions are: 1. How do I know if the betta is responsible for my snail’s shortened antennas? 2. Could any other factor have caused them to shrink or become injured? 3. Will they grow back? 4. Would moving him to the smaller tank be better than leaving him in the 10 gal that he’s in now?
And... 5. If I leave him in the 10 gal, what can I do to help control the poo situation? There are pellets not only scattered all over the place but also in giant piles, and I just did a water change this morning with a siphon and already the sand is filthy again. Would any other tank mates help?
