Someone say cat fight? im in lol...been busy at a new job guys, sorry. I dont think it has anything to do with diff or same specie agression...I've never owned a corruscans but i'd imagine they act like the 3 other specie ive owned in the genus, there just bigger
. Big cats fight, small cats coming up in size in the group fight...and sometimes ive seen an instigator 12-18"er take on a 30" when there feelin fresh. Due to accepting catfish "donations" in my earlier years i've housed large groups of this genus in particular. At one point in time i had up to 17 tsn living together in a 12' diamater pool. As the years went on the numbers dwindled and i observed. Some people dropped off 20-24" fish that were shredded to death or eaten immediatly, over night, through the week....and others dropped off 12-24"ers that were left alone for yrs. as they grew and joined the "pack"... In the end after 3-4yrs my tsn pack was around 8 fish. I rehomed a couple due to the majority being p. faciatum and currently still house 5 in a community style 1400 gal....2 fasciatum, 1 tigrinum, 1 reticulatum and one Tsnxlei hybrid ranging from 24-36"... These 5 have lived together for 5-7 yrs now and they still get into it from time to time. Never to the death (knock on wood) but torn fins and side action batteling in circles slamming each other with pec fins is a common sight in any "community" catfish tank even of the same genus. Rule #1, they choose who lives and dies, not you...lol... Hard lesson to learn, but i keep my favorite/rarer cats alone these days for a reason. Theres always a chance u find them torn to bits when the lights come on regardless of size in most cases. FME its usually the 18-20"ers who feel ballsy and start the fight. ive seen them chase around cats twice their size relentlessly but again it can go either way for no apparent reason. Good news in a "community" tank is that the agression is usually spread out, some get it worse than others, and life goes on.... I'd say let em go at it, it will usually subside....if not, youll still have one. Thats the risk taken in any community tank. I've seen a pack of Tsn single one fish out as a group and beat it to death until every last bit is consumed lol... not funny really but very cool imo to see them act as a unit. They attacked fish they lived with for 5 min and fish they lived with for 5 yrs with no discretion and for no apparent reason from my standpoint. May sound crazy, but adding another may disperse the agression and or make them team up as a group, kinda like typical schooling dithers, 2 usually doesnt work, odd numbers usually do, and in most cases the more the better
. I'd look into another set up for ur biggens, if those boys are as big as i think they are by now, id be worried they smash right through the glass lol... I can hear mine smashing lids/walls, jumping, splashing and grunting through the floor of my house. Surface feeding time is like the splash zone at sea world, when i ran my pool they threw water up to 10' out of the tank. Enough to wake me up in the night thinking someone had flown out. Dont have to get crazy, My intex pool cost me $400-500 to set up with a liner and filter and served me and the fish well for 2 yrs. Wood/liner ponds with windows are very affordable also. probably half what you spent on that glass. Keep ur "show cats"/favorites behind glass and set up something for the "general pop" fish. As always, hope my rant helps lol....
