ok,i just fed them a minute ago and they did stop to eat, in fact my smaller one usually eats more than the bigger one, she definately makes a bigger splash about it! would it help to add a school of dither fish of some sort then or just leave it as the pair of lemons? im considering a pair of 6-7 inch albino red tail tinfoils ive found for sale, but am unsure if these 2 will continue to act up. oh and is there any way of telling them apart sex wise? they are slightly different shades, the larger one has a bronzed look to its silver scales sometimes and is slightly deeper in body. just wondering. 12 volt man i do seem to be aiming all my questions at you lol, its purely due to me knowing you have owned these beasts lol! thanks for putting my mind to rest.
