My Public Aquarium: exhibit blues - how to make them?

Tentative conclusion (more likely): the catfish needs better current, more water movement and not necessarily more oxygen.

Five of seven Cuban gars have grown from 9" to 21"/52cm in 13 months, that is ~1"/month. Here we feed them Peru glass minnow / anchovy. I wonder if they are ready for 4500 gal. I always want to give each fish the biggest tank possible out of what we have but have been burned more times than I care to remember, where newcomers couldn't handle the new larger tank mates. Sometimes I could save them, other times I couldn't. Hard to gamble with the precious Cubans - they are very rare and expensive.

Sharkie the black shark was downgraded almost 2 months ago from 1800 gal to 240 gal. In the first weeks it had been receiving a non-welcome from the common pleco resident, which would chase it away from its whereabouts, especially during feeding, by trying to suck up to the shark, and the shark would escape quickly without answering back. Nowadays all is well and the pleco doesn't bug Sharkey in the past weeks, not that I noticed anyway.

There are 8 of them. At the time of that video in 2017 about 12"-16" I'd say. A couple of the biggest 10 year olds died in 2019 and 2020 and measured 17"-18" TL / tip to tip (the Cat-eLog max is crudely 21" tip to tip I'd estimate):

Sorry about the disturbing photos - the vulture catfish tank mates stay true to their name...
