Who Gives A Fish Forums

I've had sevale bettas where the fins had transparent spots, resembling pinholes, and it never caused any issues. I've noticed this more in my older bettas. My younger male, not yet a year old, doesn't have it, but my 3-year-old boy had it for over a year and was perfectly healthy until he ...

Pineapple is almost a year and a half now, 15 months to be exact.

I've reuploaded the picture to reduce the glare. Here's a clearer photo of Pineapple's fins.

I think Lachlan's response could have been phrased in a friendlier way. Instead of saying it's "totally" necessary to add a photo, maybe something like 'it would be really helpful if you could share a picture of your betta' would've been nicer.

I agree with willie32, there's a clear nutrient issue here, and it's not about the substrate, but rather the lack of nutrients. The light might also be a contributing factor. I can see why you're concerned about using fertilizers, I mean, when you think about it, lawn fertilizers come with warnings ...

I don't think the substrate's the main issue here - those first two plants are epiphytes, they grow on wood and rocks, not in substrate. The crypt, on the other hand, is a root feeder, so you could try using root tabs, Tropica or Seachem are good options.
