camtang Posted March 8, 2015 Report Share Posted March 8, 2015 Can anyone tell me the difference in these fish as juvis? Mine have an orange seem on the dorsel fin, which makes me think BA, but they look so close to JD is it not funny. Quote Link to comment Share on other sites More sharing options...
fishyNZ Posted March 8, 2015 Report Share Posted March 8, 2015 If less than 2 inches (5cm), it is definitely hard to distinguish them. However the orange colouration on the dorsal fin points to the Aequidens family, which includes the Blue Acara and Green Terror/Gold Saum (though GT are now Andinoacara rivulatus). JDs have darker colouration and markings on the body are more consistent/spread-out and pronounced. Also, the dorsal fins on JDs are usually red (edge). Blue acaras/GTs usually have one or two dark/black spots on the body. Adult GTs definitely have brighter orange dorsal fins and males usually have nunchal humps. JDs are more aggressive than acaras whilst GTs, as the name suggests, are the most aggressive of the three (based on personal experience). Can you post any photos? Cheers.

Given that a lot of people still getting confused, asking questions and mistaking one for the other, I believe having more than one way of identification provides more certainty. So excuse me if I continue to identify fishes besides their faces. Quote Link to comment Share on other sites More sharing options...
fishyNZ Posted March 9, 2015 Report Share Posted March 9, 2015 ID is easy. like P44 says it's all in the face. this is an Acara This looks more like A.rivulatus (GT) rather than a Blue Acara due to the orange color on the dorsal, caudal and anal fins. the fish in the centre of the first pic you posted is a jack dempsey imho Based on the face and body markings, red colouration on the dorsal fins, I agree it is a JD.

redracer77 Posted March 11, 2015 Report Share Posted March 11, 2015 I have Electric Blue Acaras if you are still interested. Quote Link to comment Share on other sites More sharing options...
camtang Posted March 11, 2015 Author Report Share Posted March 11, 2015 Oh yeah I forgot about that. Will work on clearing some tank space. Quote Link to comment Share on other sites More sharing options...
David R Posted March 13, 2015 Report Share Posted March 13, 2015 100% JD. Dark bars across the face are a dead give away. Their base colour can vary when young depending on whether they're at the top or bottom of the pecking order, I've seen them range from very pale to jet black in the same tank.
