If you can swing this, a longterm fix would be building a custom breading box in the background, low in height so it can be covered up front with crypt’s and Anubias Nana so it’s never seen again. Just keep the top accessible and it’s height under 4” so it’s easily hidden. You can make a low profile box or you could make a box, cut one side round, place fine filter pad to cover the rounded side and shove it in a corner. You could also make a tube that runs vertically instead but I find them to be unsightly. Regardless of shape you then want to feed exclusively inside it so the area becomes the main event for the shrimp. I’d suggest a low box with filter mesh walls. Use these to make a top and bottom, https://www.amazon.com/dp/B0BJ1S3GHR/ref=sspa_mw_detail_5?ie=UTF8&psc=1&sp_csd=d2lkZ2V0TmFtZT1zcF9waG9uZV9kZXRhaWw then cut this mesh to make 5” tall walls only say 2-3” wide, https://www.amazon.com/CKDFK-Filter-Sponges-25PPI-Aquarium/dp/B0DFS873X2/ref=sxbs_pa_sp_phone_search_thematic_btf_sspa?attrModel=exclude&content-id=amzn1.sym.cd64b36b-d00e-4d72-bc44-0c39a0cb9f69%3Aamzn1.sym.cd64b36b-d00e-4d72-bc44-0c39a0cb9f69&cv_ct_cx=fine%2Bfilter%2Bmesh%2Baquarium&include-variations=1&keywords=fine%2Bfilter%2Bmesh%2Baquarium&offset=2&pd_rd_i=B0DFS85QPF&pd_rd_r=00fe599f-c5f5-43ab-a7cc-16a9167600e9&pd_rd_w=spNuZ&pd_rd_wg=ZogHJ&pf_rd_p=cd64b36b-d00e-4d72-bc44-0c39a0cb9f69&pf_rd_r=PBCKTE9K7G571PX17NBE&qid=1781113568&rrid=PBCKTE9K7G571PX17NBE&sr=1-4-2111c337-e22b-460d-97fe-5be1c77b95e4-spons&srcWidgetTemplate=FEATURED_ASINS_LIST&widgetId=loom-mobile-bottom-slot_sptw-trending-hardlines-bottom-na-v2-t5&aref=MFNds9w9Ci&sp_csd=d2lkZ2V0TmFtZT1zcF9waG9uZV9zZWFyY2hfdGhlbWF0aWNfYnRm&psc=1&th=1 then secure the fine foam to the perforated panels with zip ties. The panels can be cut with snips to make any size or shape, but make it easy on yourself and make sure at least one wall has the fine mesh. 35ppi is good so the little ones can’t get into it. The fine blue pad is too thin and will clog over time and the blue block is not dense enough and some babies will get stuck. If you want to try tubes use this with foam top and bottom using zip ties. Use gloves when working with this mesh. https://www.amazon.com/dp/B091GD9ZWW/ref=sspa_mw_detail_1?ie=UTF8&psc=1&sp_csd=d2lkZ2V0TmFtZT1zcF9waG9uZV9kZXRhaWw&th=1
