Planner result: Not recommended. The recommended temperature ranges do not overlap. The shared pH range (6.8–6.8) is narrow, so watch for water changes. Species-specific care guidance does not recommend this combination.
Their planner ranges do not overlap (German Blue Ram: 27~30°C, pH 5.0~6.8; Odessa Barb: 19~24°C, pH 6.8~8.0), so one of them would be kept outside its recommended range.
At least 72 L and about 80 cm long, the larger of the two minimums (German Blue Ram: 54 L, Odessa Barb: 72 L). Group sizes add to the bioload, so bigger is safer.
German Blue Ram: at least 2 (best kept as a pair). Odessa Barb: at least 6 (shoaling fish).
German Blue Ram is territorial and swims in the middle & bottom; Odessa Barb is gentle and swims in the middle. Activity: moderate vs high.
