I had cleaned my tetars tank and Morpheus tank às well not completely but the tannins where gone and i saw they where not happy, Morpheus would hide he would not interact.
Well i got some rooibos tea and wow they are happy 😁😁😁😁 i added neon tetras to my tank they are my new favorite fish, bit they are so small i hope they don't pass away, the glow light tetra i added was small and is big and healthy.
