Quick update! (also really strange phenomena - I have no idea what happened)
So it's been about a while since I started cycling. Around a few days ago, I noticed what looked like small green spots growing on the fake plants, so I figured I could add a few snails and see what happened. Needless to say, the snails are absolutely adorable and they took to the tank very well. They spent their day scooting around my aquarium - a few times I thought they were dead because they were motionless (apparently these are really hardy snails so I briefly lamented my inability to keep nearly invincible snails alive), but it turned out they just like to sit in their shells for long periods of time. Overall, I think my tank is progressing along nicely.
One strange thing happened recently, however. A day or so ago my tank started clouding up a bit, which worried me a little but I figured it was a mixture of me turning the tank and stirring up sediment, and apparently bacterial blooms that can occur in new tanks while they're still cycling.
To illustrate the strange thing that happened, here are two images of the tank taken 20 minutes apart. I'm thinking maybe I should change the water and remove that strange cloudy layer of... bacteria? Sediment? Sentient organisms? All the cloudiness sort of just coalesced into one layer, and it's been slowly dissipating completely and leaving my tank clear once more. I am absolutely flabbergasted.
Aside from that, here are some pictures of my really cute snails. Apologies for the bad phone camera quality.
Forbidden snail romance?
One very cute little snoot.
