Try feeding her some frozen deshelled peas.
Also you really need to rehome that pleco.
You can give all of your fish peas, it helps clear them out.
The pleco will get stunted if it already hasn't.
Yes plecos love cabbage!
The pleco will grow to around 24 inches and needs a 100 Gallon tank at least!
'Fish only grow to the size of the tank' is a myth, there external body stops growing but their internal organs keep growing causing a slow and painful death, the fish release a hormone into the water which stunts them.
Yep thats what UV's do, although they are not really needed.
What I normally do is warm them up in the microwave in a bit of water for about 30 seconds, then de-shell them and break them up small enough for the fish to eat.
Then drop it in
I feed it to them once a week, I feed them 2 peas, broken up into bits.
Depends on the fish im feeding,
