Hey , ive had the asitica for awhile and one of them is really shy , its the bigger one tho he claimed a hiding spot or she i dont know what it is but they seem to be really shy was same thing with my SH when it was small theyr both pretty big asiaticas i wish i could show u a pic but atm its really hard to catch a pic with the hiding they do usally the big one hides in a plastic wood thingy that is just like a cave , i know that ur gonna say "ur temprature is too high" but i really dont think its about that since one of the smaller asiatica usally shows himself and if hes hungry when its food he will go nuts to get it , anyway my micro and the bigger asitica has been showing some aggresion towards each other but it settled down it could be taht my space in the tank i got is not enough but im just about to order a special size tank so that wont be a problem , when my micro out grows it for real , and then i mean really huge he will probally get a new home in the local aquria swimming with 1 meter long redtails , and tsn / pacu etc but thats still a long awhile to go and i dont want to give him up unless hes certain to not be eaten , anyway my asiatica is shy when taking pics / trying to watch them , ive seen them out when its nothing loud or person trying to check out at the tank but if i go close with them camera they would just both hide!
