Another thing, Why at the petshop like 20 Gouramis are in the same thank without hidding spot and for most of them they look in good shape?? did remove hidding spot help the fish to be less aggressive?
*PEACE!* it is only a question
lol i understand what your saying. most petstores WAY overstock their fish in tanks, so in that being they stay small. while they are small they should be fine getting along with each other because they are a lot more peaceful. i didnt notice my gold or opaline getting really aggressive until they reached approx 4". then they started getting very territorial. it was sad when i had the dwarf gourami because he got the $h!t beaten out of him. i watched my gold and opaline start to bite off the fins. i also watched him take the dwarfs (feelers or whatever the hell those long tenticle things are) right off and it floated right to the top. it was so sad. i felt bad. i tried to find him a new home but he got murdered too quick. after the dwarf was dead the opaline and gold started fighting and since the opaline was much bigger he stressed the crap out of the gold. then i got rid of opaline and tried to find a blue the same size as the gold and put them together, then the gold got WAY aggressive and killed the blue. i could never win with it. and i have a 55. thought there would be enough room but guess not. since then i have gotten rid of all gourami's.
now dont get me wrong EVERYONE has there OWN success stories with fish that everyone else and studies say arent compatible even by keeping by others but somehow some people get those special instances and i have with some fish in the past where they can get some fish together and they become great tank mates. i ended up getting rid of a pink kissing, opaline, gold gourami away at different times because the bigger they got the more they started being mean to all my other fish, and ive spent some money on fish in the past and didnt want to lose them. i also had SOME success with a figure 8 puffer with the gourami's, my sharks, my school of platinum green, green, albino, and regular tiger barbs. but then i realized i was new to the fish keeping world and realized i was EXTREMELY overstocked so then i started downsizing.
now i want to get another 55 or larger and split up my sharks. i want to put the rainbow shark, bala shark, and gold algae eater in a separate tank and add some cichlids and in my current tank i want to add some cichlids with what i have and a black knife and in the other tank i want to add a brown knife. sorry for so long just thought i would share my experience with you in somewhat of detail/history so you might have a better idea what you might be in for, IF you have the bad luck that i and others have had
