The EBJ genetically are weaker than the Rocio Octofasciata. I purchased 4 last year and lost 3 to internal parasites. I suggest treating them in a quarintine aquarium.Would you suggest for me to get a electric blue Jack Dempsey. I hear they die a lot. Is this true
For the past month roughly I've had the smaller of the 2 in a community tank of tetra and smaller fish. The larger of the two is actually female I believe. The smaller one pretty much roams around the bottom of the community tank oblivious to the rest of the world so I'm not sure how great his vision is. As far as treating the popeye I've done one course of erythromycin (medicating the food) and now i've been doing Epsom salt baths to try to cure it, but in the past I've never been able to cure popeye that wasn't from the fish taking a hit of some sort. I've spent a lot of money trying on more than a few fish and never once have had the popeye go away unless it was from the fish scratching their eye or taking driftwood to the eye etc. ( which is why I don't use driftwood in tanks with big fish anymore) have you ever had luck treating popeye that was being caused by kidney related fluid retention? I don't have much faith in the little guy making it very long tbh. It's just odd to see a fish seem so healthy yet not show any signs of the nourishment I see him getting.Females grow slower than males. Which is common but stands out more in a slow growing morph.
If a fish has a problem, such as developing Popeye, their system will spend energy on healing rather than growing.
Yes I've seen individual that didn't grow, and its usually bad news. Sorry.
I would suggest isolating the non-grower to treat the eye and/or parasites.
Also, if the small one turns out to be female, she'll do better if kept away from the male until she grows up a bit more. When a young female's system puts energy into reproduction, thats energy not going into her own development. Again, thats usually not too big of a deal, but until we are dealing with a fish already compromised.
