Thank you Ken.
What is your opinion regarding adding a few megalops to the group

That was actually my next growout fish! I love them. Don't they need brackish water?
I can get juvies of megalops cyprinoides, caught in full fresh nearly 50-60 km from the sea.
Adults are generally found at sea, but young inhabit river mouths, inner bays, and mangrove forests. In freshwater, they occur in rivers, lagoons, lakes, and swampy backwaters (Ref. 2847, 44894). Tolerate a wide pH range (5.2-9.1) (Ref. 44894) and salinities from 0 to 100. Mainly diurnal (Ref. 7017). Predaceous, feeding mainly on fishes and crustaceans (Ref. 5213). Breed offshore, possibly throughout the year. Larvae are transparent and resemble larval eels (Ref. 13337), but with a forked tail (Ref. 167). Juveniles commonly enter freshwater (Ref. 44894, 48635) in clear or turbid water (Ref. 44894). Known to breath air, rising regularly to the surface to do so. Cultured in ponds, the fry being sourced from the coasts (Ref. 7050). Popular angling fish (Ref. 3969). Edible but not esteemed (Ref. 3969).

I've no time to look for the citation but my personal database says they grow to 1.5' in fresh and 3' in salt (albeit FishBase cites 5' max) and at the time of writing I had found this info trustworthy to be included.
Anyhow, my pair has been in fresh for 3.5 years. Stopped exactly at 1.5'.
