Every two days would be fine.

Hey Sakura, wha kind of water change scheduale would u recommend for a one gallon bowl with 1tsp of epsom salt?

Tarris seems to be doing well, just about 1cm of fin regrowth already, but it seems like his scales are on verge of starting to barely rise again... I got paranoid and put in 1 tsp of ES hope that's okay, and he also seems to be swimming slightly different so mayb that would help with his swim bladder

Thank you, Maggie. How is Tarris doing?

Happy be-lated birthday!!!! :d

Yes, that's fine. :)

hey Sakura, i was wondering if it's okay for me to only do water change for tarris' 1 gallon every other day while he still has a super tiny bit of fin rot left (it's not getting worse but it's just there and not growing or fading away yet appearance wise)

I use Penn Plax Cascade heaters. Hagen Elite heaters are also good. Both come in 25w which is fine for a 1gal kritter keeper. I believe you can get both from amazon too.

Sakura, I have a friend who's looking for a good heater for her 1 gallon critter keeper. I was wondering if you have any good suggestions. She tried searchijg up for some but didnt find any that didnt have negative reviews. Thanks

Sakura, I was just wondering if you could comfirm that a chunk of my bettas fin gone is due to fin biting. It starte yesterday when it was becoming skightly shreded. He's like a biege seethrough HM so I could easily look for black outlines for fin rot and i dont see any. And just now a lot more of it is gone. Just the rays are left and its like half of the tail lengh wise of that part thats missing is gone. Im really sure i safe proofed everything and I'm pretty sure the filter didnt take away the chunk though there is this one split part on the lower fin which im unsure about to whether thats biting or just split open with tiny current and rapid glass surfing. Anndddd the best way to treat this is stresscoat, clean water, rearrange everything every water change, try adding a ping pong ball for him to play with, but is there anything else I can do? I'll try to send pic tmrw. Thanks for answering
edit:PMed you a pic just now, andd yaahhh thanks again
