So Ive had my new jardini for about 2 or 3 months now and he's been doing fine in the 55 gallon with his tankmates. He's 5 inches and out of no where he started chasing my fiances gold sev and attacking it. So the sev is her favorite fish because its got a birth defect so I said I'll get rid of the jar. Really sucks but better to get rid of it now before he turns into a killer. I replacing him with a ornate and delhezi bichir.
