I’m on my 3rd Silver. It’s about 9”-10”. Hard to eyeball measure as it won’t sit still to let me stare at it. Lol. I haven’t been able to grow out past 10”. My last one got serious lot obese. Likely some semi shortbody thing going on for some of these.
The past 6 months I’ve been trying the rock salt up to 1.5 cups per 100g dosing. Got this advice from my stingray, dat, bichir buddy who’s been dosing 2 cups per 100g for years. All my other larger dats and bichirs seem to like this salinity. Hopefully I can get my current silver at or over 12”. Just sharing my silver experiences here.
