Newbies. Need help with Dwarf Sagittaria

Well.. there is something wrong with my rasboras... 1 more died. Only 1 left.
The neons, SAEs, Kuhli Loaches, and clown pleco looks good. No strange behaviours.
Btw the last Rasbora look ok too...
 
Neon Tetra Disease... I just quarantine the last Rasbora. Hopefully no other fish got it...
 
I'm sorry you're having issues with your rasboras, Can you post a pic of the ill fish? If it truly is "neon tetra disease" there's nothing you can do...
 
It doesn't look like NTD to me, but your rasbora is ill with something...I'm going to guess a bacterial infection just because it's fairly common; maybe columnaris but not like I've seen. I don't have any experience with a fish presenting those signs, I'm sorry.

Hopefully some will have a better idea & chime in soon.
 
Sorry for not updating this... Lost all my rasboras. But the rest are ok.. havent lost anymore fishes. Everything looks to be good for now. Just some algae issue.
 
Everything looks good now. My only concern is all my leaves have black stuff on it. Algae?
Or is it a deficiency?

I'm sorry about your rasboras, hopefully nothing contagious.

How long are your lights on now? Like I said (somewhere) before, some leaf loss is normal. But if you lights are on more than 6 or 7 hours, cut back a bit more. It could be diatoms too, a brown algae coating in new tanks. The new growth looks good, you may just have to wait it out. I even see a couple new sags & maybe a new crypt too. Patience!
