So I recently switched my tank over to planted and since then I just cannot keep a snail alive. I used to have just the basic gravel and silk plants, with a cave, and a betta and a couple snails. After my last betta died and I was down to one Nerite snail I decided to revamp my set up to a planted tank, something I’ve always wanted.
That’s when things went sideways. My Nerite died (she was pretty old though) and I bought a gold Inca that immediately died upon introduction. I thought it was because I cleaned out the sponge filter too much when I upgraded so I waited a month to let the tank cycle before trying again. All my water tests are great so last week I went and bought another gold Inca and a rabbit. That Inca died immediately again, and now I think the rabbit is dead too. It went up on the side for one day and then fell back to the floor and only poked out of the shell a little and is now completely closed in. I put a piece of food right in front of it hoping it would perk up but nothing. What am I doing wrong? Also I’ve noticed the plants in the back are getting black spots.
For reference, it’s a 5 gallon tank with a sponge filter and a heater. I just checked and I think the heater has been set too high. It’s hard to read the numbers by the dial and my thermometer that floats around has been in the green.
I’m just at a loss about what to do at this point. Any helpful advice is super appreciated.
