5 week update
Looking for some feedback...
The tank is doing alright, but it's not where I want it. Some of the cryptocoryne in the tank is melting, and I'm not sure why. It waited several weeks to start melting, and the only major change I made was to add a few harlequin rasboras. The plants most severely affected are right in the middle of the tank, directly under the light. The plants on the periphery of the tank look great.
Some theories... The lighting is much stronger in the center, so maybe I have enough nutrients to support plants on the periphery, but not the middle? Or maybe it has to do with circulation. I notice the water movement is better around the edges than in the middle.
In any case, I have been aggressively trimming leaves that start showing holes and melting. The plants are still putting out new growth, which I notice is much darker.
Also, I'm noticing some yellowing on the leaf tips of the crypts. Sign of nutrient deficiency, or something else?
Added 5 harlequin rasboras. They're doing great.
Added 3 cherry shrimp and 1 amano shrimp (2 weeks after adding fish). They are not so great. 1 cherry shrimp died, and the amano is MIA. I'm disappointed - I don't like killing livestock. Not planning on adding any more for a while, at least until the tank is more fully matured.
Added a bunch of java moss
Removed the susswassertang. It didn't really fit with the overall feel of the tank.
