I might be wrong but I have a 20L and bought 2 Leopard Corry's. From 3 LFS
, none said I need to have 6 at a time. 2 is good. They are very happy little buggers with my 6 fancy guppies.
UGH! I am going through a bacteria bloom! Hear one thing then another. My parameters are PH steady at 8; Amon. not quite .25. My first change ever I think I over did it. Had cycled the tank with established sponge for 3 weeks. Then added gups. and Hornwart. It made mess & died. Got 2 corry's. 4+ wks. cleaned, threw away plant, rinsed sponge in 5gal I took off. 2 days got cloudy, 1 wk later took off 3gal. No rinse sponge. Looks awful but all are fishies healthy. Feed only what eat in 2-3 mins. 2x's day. Went 2 days no fed. Need to get nitrate & nitirte. tested. Wished I had gotten master at petmountain but found the site to late. Guess I am supposed to wait this out, no change unless parameters out???
