Can Discus live with Flash Pleco (L204)?
Caution — with care
Why
- Almost no shared temperature: Discus wants 82–88°F and Flash Pleco (L204) wants 72–82°F, so only 82°F suits both — too fine a margin to actually hold.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
Sweet spot: both do well at 82–82°F and pH 6.5–7 — aim there.
