He's had a few rough weeks, else he's quite calm and is even ok with me putting my hand inside the tank.
I had added the crenicichla lugubris to this tank, the crenicichla for some wierd reason, even though well fed had a liking for gatf scales, used to hit the gatf and then snack on the flying scales.
Since then the crenicichla has been moved to a different tank
That's totally nuts about the pike cichlid... What in the world?... Goes to show our helplessness sometimes...
But the hand-in-GATF-tank is huge! Wha-a-at?? I can only dream of mine behaving so well. I must tiptoe at a turtle's pace around their tank and do everything slowly, approach at a 90 degree angle at one end of the 8' tank, gingerly raise a lid, carefully place the feed in, slowly close the lid, and slowly back up retracing my steps straight away from the tank (God forbid I walk along side the tank anywhere closer than 15 feet! That's a recipe for a nuclear meltdown...) and they still would freak out half the time, or least some of them.
Imagine what transpires when some cleaning or furniture rearrangement is needed. It's the sky is falling... the sky is falling... everyone run for your lives! Jump out! Hit lids! Hit walls! Hit furniture! Hit his hand! Hit tank mates! Hit each other! Do whatever it takes to knock yourselves out and die!
Never when in 240 gal have I had an ATF show that they know where the feed comes from. They have no association of a person with feed. No room for adaptation and learning. No operative memory. It's all on a hard drive and that's that! There ain't any Pavlov in these dogs, it seems. None. Period.
I see your tank is pretty small. Is it so it doesn't pick up speed?
The only ATF that have done well for me are two ~2' VATF that have gone into a 4500 gal early in life at around 8" (in fact 5 VATF went in - I paid for this haste dearly with losing two to predation... and a third one at ~14" I suppose had been killed later by the two that remained). Everything in 240 gal is a disaster sooner or later, even with side panels padded with filter mats.
Hardwall "smallish" tanks are not for these fish. They need either a huge tank or a softwall pond or at least as
fishtankphil
is doing it a round hardwall tank.
