well my goldies were causing a lot of strife, and fought and even started bullyign each other to the point they killed one of their tank mates, after weeks of trying to find out why it turned out that the heat of the tank could have been a stressor and was leading to bickering or fighting, either way, they are now out, and in a storgae box awaiting their new home, the fnacies will be going into my bedroom in a 30-50 gallon, the comets will be going into a pond, i just couldnt part with them! the guys in the big tank, the 2 lemon fins (1 about 14/15 inches and 1 about 12/13 inches) and the 1 male mouth brooder who is about 10/12 inches seem to be settling in fine. would you say this tank is now fully stocked? its 6 x 2 x 2, but i have no idea if these guys have mroe growing to do as all info i find on them is conflicting, ive found info saying lemon-fins grow from anywhere between 6 inches fully grown to 18 inches fully grown, as mine are already so big im tending to keep towards the larger estimates! its just ive seen some gorgeous little oscars, and ive never really taken much interest in them, but these were really pretty and followed my hands where ever they were on the tank. if i did get one, it would just be the single oscar, then the 3 fish that are in there (my friend wants me to take her 6 inch rainbow shark but im not sure if it may get eaten) i just dont know whether to leave the 3 as they are and maybe get my friends rainbow. oh and just so you know, i will never be able to up-grade the tank, this is as big as i can go.
