45 reassess

My 45 has been struggling a bit again. I try to feed the tetras lean and give the angelfish her own food -she's good at following my hand above the water and will even leap a bit to snatch a bite from my fingers- but the tetras are so quick to dart in and take food right in front of her nose. Sometimes this seems to make her angry- after feeding time she will plane around the tank making vicious dashes at the tetras. They always evade her.

Vals have grown more and more- the longest reach all the way across the surface now. I trimmed out some older leaves. To my surprise hornwort stems I weighed down haven't deteriorated- they're thriving. I trim them back when they get too tall, and have tied down some more. Angelfish doesn't really like those thickets of stiff needles and stays on the side where the vals are.

The tank had lots of unsightly black spot algae, especially on anubias. Newer leaves look fine so I trimmed off older ones, cut one rhizome back and tied the piece onto a new spot. I accidentally spilled my bottle of prime a week ago, and kept putting off going to the store to buy more, so the tank missed a water change. I did two partial wc this week, and made sure to rinse out one of the sponge filters too. 

But the angelfish has another fin edge deteriorating- the anal fin this time. All the tetras look totally fine, but any drop in water quality she seems to start to get fin rot, which concerns me.
