Why is it whenever I take a photo, there's always an aquarium co-op product there to ruin it?

I zoomed in a bit, and yeah it looks like there might be fit rot as well. Though both fin rot and cotton mouth are bacterial infections as far a I can tell by googling them, so I'm not sure if I want to use anti-fungal. As far as a lump I don't see one, just the bit of silver they all seem to have at the base of their fins.

Here is a video, might be a bit easier to see than that pictures:

We've had these rasbora's for about 6 months. This afternoon we just noticed this on one of them. Is this cotton mouth? sorry for the blurry photos, these guys are difficult to get a fix on. A couple questions: - I read that the bacteria that causes cotton mouth is present in all aquarium. If this is the case what is the point in separating it? - I have Melafix and Imagitarium bacterial infection remedy, I can dose the whole tank with all the fish or the fish separated out into its own tank. Would either of these medication be a good idea to use? Tank setup: 20 gal long, planted, inert substrate, medium light, no CO2 parameters - tested yesterday: 0 ammonia and nitrite, 10 - 30 nitrate (depending on fertilization and water changes), 7 PH, 6dgh and 2dkh. temp: 78f

Thanks everyone for your replies. @ChefConfit Since the wonder shell I have done water changes, but I also added dolomite rock to the tank which leeches calcium and magnesium into the tank. the GH has not dropped below 6dgh. Also some water sprays onto the lid and when the water evaporates I still get some white powder left over, it's a safe bet that is is calcium. @Kirsten I have a betta in the tank, I did see him pecking at some of the larger ramshorns, but I've never seen him bother pond snails. I might try moving the ramshorns to another tank and just have that be a snail tank. It's funny, I added cherry shrimp to the tank on a whim to see if the Pete (the betta) would go after them, and he seems totally apathetic to their presence @H.K.Luterman thanks for the food suggestions, I'm going to look into something to feed them specifically. I also added some shrimp and I bet they would also appreciate the algae and calcium. @Dawn T Initially, 100% a calcium deficiency. My tank had 0 gh and 0 kh. I think that's what killed off the big ones, now I think it may just be a lack of me feeding them and possibly my betta attacking the ramshorns.

It has been a while since I posted last asking for some water chemistry advice. Since then I have managed to get my water parameters fairly stable at 0 ammonia and nitrite, 10 - 30 nitrate (depending on fertilization and water changes), 7 PH (up from 6.6 avg a few months back), 6dgh and 2dkh. I had some hair algae issues but got that under control as I was dosing too much fertilizer/too much light. One issue I still have however is that my ramshorn snails have all but gone extinct, the only ones that are still around are all tiny (< 3mm diameter), and their shells look stunted. The pond snails are also looking a bit ragged and their population has declined. The Malaysian trumpet snails however seem to be doing great and have a large stable population. What am I doing wrong here, a few questions I have: Are the ramshorn and pond snails just getting out competed by the trumpet snails? Are the ramshorn and pond snails malnourished because I am not explicitly feeding them anything regularly? Why are the ramshorn snails shells so wonky, am I missing certain trace minerals in the water column? I put a miracle shell in and it did not seem to help the snails that much other than making my dGH around 12. My current running theory is that my PH was too low for the snails I bought initially, which caused the first generation of them to get holes in their shell and eventually die off. The baby ramshorn snails, now that the PH is better, are getting out competed for food by the trumpet snails, they are malnourished and dying off before they reach maturity. Pond snails hitched a ride on a plant and took over for a bit but then also started dying off, the shells of the baby snails never get path the transparent stage. I think these are now also getting out competed by the trumpet snails. I have included some pictures, all taken today. I can send links to larger resolution images if requested. Any suggestions/advice anyone has as to why my ramshorn snails are not thriving would be greatly appreciated.

I started a thread after I made this today, I should have just posted in here. It may be ugly, but I'm proud of it.

Was looking at adding dolomite rock rather than crushed coral, since I've read is increases GH more than crush coral and also increases KH similarly to crush coral. Anyone have any experience with using Dolomite?

Thanks everyone for the help, for the short term I'm just letting things continue with a 20% weekly water change. Will probably add crushed coral or dolomite to the hang on back to raise the KH and GH slowly after water changes. I'll also look into the salts, tums and Seachem Equilibrium, but for now I'm trying to make changes slowly since everything (except the snail shells) seems healthy.

Background 20 Gal Long tank Contains Live plants Ramshorn and Malaysian Trumpet Snails 1 betta and 12 rasboras Tap water: PH 6.6 - GH 25 ppm - KH 0 ppm I added one 2/5 ounce wonder shell about a week and a half back to help my snails as their shells were starting to look unhealthy. Since adding the shell the GH as slowly increased to ~300 GH. This value concerns me, do I need to lower this value? If so, I remove the shell and do 10 % water changes once a week until normal (I'm worried about shocking the fish if I lower the GH too rapidly)? I was also having issues with my PH slowly dropping from 6.6 to 6.3 over time between water changes. Would replacing the wonder shell with some crushed coral solve the PH and GH issues. If I'm reading correctly it should slightly increase my GH to make my snails happy and maintain the PH at neutral by adding some KH buffer to the water. Am I understanding this correctly? I was thinking about adding some crushed coral to the hang on back filter. How much should I add to that? Most of the hang on back is filled with sponge/bio rings, should I replace the bio rings with the coral? Basically how much should I add for a tank my size, I'll figure out where to add it. Thank you in advance for anyone who decides to help out.

yeah, I like the little ramshorn at around 1:40 near the floating plants in the upper left. It will float to the surface and ride the currents around to get to where it wants to go quickly. I've seen it do this multiple times and it's the only one that does it 😄.

At around 1 minute in there is what looks like a worm swimming around on the right hand side of the screen. I read that snails can carry parasitic worms, can anyone confirm if these are or not? I also see a lot of baby snails, but the wormy thing looks different to me. The tank contains ramshorn and trumpet snails.
