Sudden Aggressiveness

[osiris]

my, smaller of my two severums has suddenly become very aggressive towards other fish and anything that goes in the tank every now and then like a magnet glass cleaner. its frightened away most of its tank mates and, well, i dont want them all to hide so, could someone please explain why this is happening or any possible solutions.

Thanks

Could be sexual maturity, maybe stating tank dominance. Also, you may just have a mean fish.

Hey, is there any chance that she has laid eggs somewhere in the tank? as it sounds like usual protective breeding behaviour,
are there any other Sevs that he/she isn't bothering?

If you put your hand in the tank does he/she try to attack you? < if this is the case then it would almost guarantee she has eggs somewhere.

Yeah it us very likely to be eggs if you get attacked by them, as thats what my convicts are doing so i always wear gloves lol.

oh rite, thats exactly what happens so i guess she must do. theres no other sevs in there apart from herself and the male, what should i do now? should i take them out? also where do sevs normally spawn? i cant see any obvious eggs anywhere....

Thanks

The eggs are laid on any flat surface, usually a stone or maybe on the inside wall of a cave, or on the actual filter or heater

ok, cheers, i cant see any, its quite likely that theyve been eaten due to the other fish in the tank so i guess il just leave it, im asuming that my sevs will go back to their normal selves or either spawn again.

thanks alot
