Can Endler's Livebearer live with Blue Phantom Pleco?
Caution — with care
Why
- Large size gap (Endler's Livebearer 1.2" vs Blue Phantom Pleco 7") — the bigger fish may eat the smaller one as they grow.
- No overlapping water hardness: Endler's Livebearer wants 10–20 dGH but Blue Phantom Pleco wants 5.5–7 dGH.
Sweet spot: both do well at 75–82°F and pH 7–7.6 — aim there.
