Bought a couple ghost shrimp (Palaemonetes paludosus according to tank) from Petco yesterday, somewhat amusing to watch Betta chase them away from his pellets, woke up to big ragged chunks missing from his tail!
His tank only has live plants and small smooth driftwood pieces--could ghost shrimps be nibbling on his tail fin at night??? Their claws are so tiny! Or is he somehow ripping his tail when chasing them away? Or some unrelated cause that coincided with new shrimp? Water has been stable and just did a 50% WC before putting shrimpies in.
Thinking of switching out for red cherry shrimp.
