Some of the personal observations, and I can't guarantee the same results for others.
Do CRS hide most of the time?
Not really, and yet I never see all 6 of them
. In fact they are on the move a lot. They are funny and interesting to watch, sometimes sitting on a rock along or "fluffing" fountain moss in group of 3 out in the open. My fish can't hurm them, and lighting is low so everywhere they go It's semi-shade, I suppose they feel safe.
Are Boraras shy and timid ?
Not at all, they have no predators in my tank, and I stare at them so much they're used to it now and come right to the front.
Do Boraras Brigittae school? What level of water they prefer?
When scared they all come together in a tighter school otherwise they seem to go off and explore/hunt solo or groups of 2-3. Maybe 10 gal is small enough for them to see all their friends and not feel lonely. They are everywhere at once and each comes to top or bottom or middle, again maybe my fish tank is not deep enough to notice any preferences.
Do they like strong current?
So far its like a fun work out for them,they swim into current and *woosh let it carry them towards front glass, turn back into the current and do it again. Then they get tired and hang out on the right side where current is slower. also I'm sure I should mention that my filter spits out some yummy worms (not sure what they are, but they are small, white, free swimming and thrive on plant decay they live in filter and also in dense moss). So yeah, fish spends lots of time in the current catching them.
Are Boraras Briggitae really that iridescent red?
Males are for sure. All of my fish are bright red but some show intense Raspberry red.
Are they picky eaters?
Well, they were tank raised so they excepted regular tetra flakes. They also couldn't get enough of what was intended to be a special treat for shrimp - boiled carrot and lettuce
Speaking of shrimp one never forgets first molting, hehe. I saw clear as glass motionless body, and panicked. Why? What have I done? But it's no fare you just got here!!!!! Did a count of moving fellows I could spot - all 6
