Took about an hour to change out the gravel for aragonite.PXL_20211021_174214322~2.jpg

These guys went from swimming out in the open prior to redoing the tank to hovering over a shell and disappearing when they sensed any entry into the fish room. Shy is an adjective used in every description of them and they are indeed. I need a dither fish but I want a L. Tang dither. I would really like to add N. leleupi or Julidochromis ornatus. Brichardi maybe? Open to ideas.

N. leleupi and a N. brichardi are too aggressive for the A. sumbu shell.
Smaller Julidochromis can be compatible but I don't think they will work as dithers because they will spend most of their time hiding in the rocks.

How long is your tank? 48"? With some higher rocks and a more dim lighting Paracyprichromis might work.

Another approach that could work are more mellow shell dwellers and more shells. Normally I would not suggest species that will occupy the same habitat but I know somebody who successfully keeps the combination of N. brevis, Telmatochromis sp. vittatus shell an A. sumbu shell in a tank 32*20". There are at least 60 shells in the tank.

In both cases I would not expect any A. sumbu fry to survive.

Yes, the tank is a standard 55g (48 x 13 x 21) with more than 60 shells. I have the mellow shell dwellers with the N. multies but I would like to add some diversity to my L. Tang species and provide a comfort fish so that the Sumbu will hopefully show themselves more readily. I have had cyps and would possibly entertain getting them again.

N. multifasciatius is not mellow at all. They are way too assertive for A. sp. sumbu and will tanke over their shells after some time.

Dave's Rare fish and I find this "Ophthalmotilapia boops Nkondwe Island." BOOPS, I gotta say it the best Latin naming convention ever :ROFL: and I now have an irrational need to add this fish to my collection.

Nice looking fish but total psycho as some people would call it. They need at minimum a 5' tank. If you want to keep more than one male 6'+.

I have seen only 1 of the dwarves consistently so I did a water change and pulled all the shells a few at a time. Using my headlamp I was able to candle the shells and find 7 dwarves. One even looked to be guarding eggs. I removed all but 30-40 shells that I spaced out in groups of 5.PXL_20211213_220019072~2.jpg
