having had more troubles with my divided than anywone else on here im guessing, i can outline what the cons are anyways. the pro's have faded a little since i've seen how much better they do in critter keepers.
now, i guess my problems were already programmed because my 32g long is split 6 ways, which is too much imo.
first couple of weeks went good in my divided. 3 fish, so the tank was half stocked. water stats were all perfect and stable. added more fish until i had the compartments filled. all went well for a while until the 1st started to bite its fins. i swapped him to the corner compartment thinking he needs some space but it didnt improve.
it wasnt long till the 2nd started to bite. however, i ignored it and they stopped after 2 weeks or so.
i then had to move house, which all went well and i set up the tank again with no problems.
then, disaster hit.
an unknown illness caught draco, my super delta dragon. i took him out but he died just 2 days later. then, it spread to another 2 fish withing a few hours. i took the tank apart and put my remaining fish into critter keepers where they were doing fine. another that had caught it, recovered.
my point; if something goes wrong in a divided, you risk your whole stock. thats is a con that weighs out all pro's imo. hence why i wont list the obsious pro's...
im now setting the divider up again however, as i believe the illness issue was my own particular fault...
the flaring that has been addressed is indeed stressfull for the fish at first, but after a few weeks mine had adjusted. infact i think to a certain extent mine enjoyed each other's company. so it seemed
