Ok,the fish is 8.75 inches,and he was 6 inches when i bought him in jan 08,he reached this size in about three to four months so i thought ok thats not bad,but not brilliant,and at this point he would eat small mealworms which he took after a day in the tank.
When we first got him he was in the 20 inch X18x13,which was more than double his length and he seemed happy as he was growing ok but then we got the 2x2x2 and he went in there and was doing fine.
At this point he was about 8" then i got a 3 inch dat and put him in there with him,and he carried on growing with the dat in there,the gar would eat the mealworms and the dat would eat krill etc,then i saw the dat just have a little nip at him,which didnt seem to bother him,he didnt swim off or anything but over a week or so i saw the dat do this two or three more times so he went in the big tank,but the gar was still eating and didnt have any split fins or anything so there was just him in the tank for a about 4 or 5 months,this the period i noticed he didnt grow and one day stopped eating the meal worms and has not eaten one since?
I tried him on crickets which after a bit of coaxing he started eating them,but after about two weeks of perhaps one a day,he just stopped eating them too?
When i put them near him as i always did,he swims off like hes scared of it,and this is what he does if you offer him anything else but frozen or live bloodworm,and he will eat this morning noon or night at the top of the tank and when the worms sink he goes down and eats on the bottom.
The other foods ive tried with no success,and im sure i will have forgotten some but you will get the idea,are frozen large krill,small krill,fd krill and fd shrimp,frozen and fresh prawn,lancefish,cockle pieces and pieces of mussel and frozen mussel,beefheart,artemia,brine shrimp,discus food,etc etc.
The pellets and flake ive tried are tetra colour,tetra prima,bloodworm pellets,big and small carnivore pellets,sinking and floating cichlid gold jbl aro pellets,hikari aro sticks etc.
Crickets of all sizes,small and large mealworms,earthworms,im sure there are more but i think you get the idea.
Ive tried feeding the frozen thawed and frozen,and soaking them in bloodworm,and ive tried this with most of the foods above.
The light is a single 15" tropical bulb,with 60% of it covered up so not bright.
The filtration is an internal fluval,and a 380l huey hueng sponge filter and a bubblebar,and ive put the fluval so that he can sit at the top and hes not in the flow but the flow isnt very strong anyway,the sponge filter is more powerful,i was going to upgrade to a 205 or 305 fluval but think they may be too powerful,and like i said i know the water has got a bit of amm in but usually its zero,ive tried big wcs and small wcs and leaving it for like two weeks but this didnt make any difference,he does seem quite happy swimming about but its like his brain is programmed not to recognise any other food lol!
Also if i drop a worm in or a pellet or whatever and it lands on him or right next to him,he swims off like hes scared of it!
Ive tried feeding with the lights on and off and the room light on and off and even a small lamp on near the tank but he just doesnt show any interest at all,not even mouthing it and spitting it out he just ignores it,im going to try some bloodworm pellets soaked in bloodworm again.
The tank is in a very quiet part of the house with no through traffic so hes not getting spooked.
Think ive covered everything,hope this helps.
cheers steve
