I've always found I lose one or two rainbows a month to jumping in my open top tanks . However, I've always wanted a big school of praecox... they are common, but F1 or F2 look incredible. What variety are you thinking about?
Yes, I know a few will leap to their deaths.
I lose a cardinal about once every 1-3 months or so.
They are not $$$, so I'm okay.
Not sure on the variety. I've kept some bosemani for client's, but have not kept much for myself in a very long time.
NG threadfins was another idea, small and delicate etc.
The other idea is a type of Boras.
Too much reds though, I want something a bit silvery and flashy.
It's an active colorful tank, so..........many many choices here.
