I decided to do a 'covert' late night feeding time for the little ones, they didn't know what was happening until I turned the lights on in the room and they saw me going over to the tank ;)
Usually they would ALL 'pick' away at my hand/fingers or my arm when I put it into the tank but I think they were still sort of sleepy as this 'covert feeding' was done 4 hours past the last feeding time that they have and they were in the dark for those 4 hours etc. They still came up to take food from me and a lot did peck away at my fingers.....I'll have to get a morning feeding video uploaded - they go TOTALLY nuts and have NO fear of human interaction at all !
Note the air pump and the simple aerator stone at the back of the left side of the tank - it is a small one that just bubbles away and does not create a current, and also note at the end of the video I show the two sides of the tank which are covered in GOOD algae (the back of the tank is not shown but that has NEVER been cleaned and is covered in GOOD algae). I usually clean the front pane of glass as well as both of the sides but never the back pane of glass as it is GOOD to leave the algae there for when you do a partial water change. Plus comets and fresh water fish in general just LUV eating live algae !
This is a 180L aquarium and I feed these little ones 3 or 4 times a day as I have heated the water up a tiny bit. I last cleaned the filter just over 1 month ago and have not done any water change at all in over 6 weeks (I will be doing a partial one this coming week though). (less info)
