looking back, at 14 years old with my 1st tank (10g) I circled what fish I wanted. Water was warm (no thermometer). No fish survived by the morning. When my mom did give me a thermometer it read 100 degrees and the tank was way overstocked. A year later I tried again, and I had my first good tank of a paired goldfish at 15; they were awesome. I learned soooo much. Never had any problems with them, until they got dropsy later on...by with this tank, I set up pond snails, gravel, live anacharis plants...it was awesome and it took off. I learned so much from this 10g goldfish. I have so many pictures from them 

so....fast forward 20 years...I taught hubby everything, I mean everything I know of the hobby. I even kept fish journals of when tanks where crashing and I couldn't figure out why (parasites, fungus/bacterial infections, salt dips, etc) I said this brief history so you know I am not a newcomer to the hobby...and please do flare at me for my question, but reading through the previous posts raises my own concerns...
looking at my sig- you know what tanks and fish I have, briefly speaking. They are not growing as they should (rtc, IRD, tsn x achara, giraffe, etc) or maybe it's just me... If I start to feed them as they were (before, as their primary feeder), will they start to grow "normally" again, or are they stunted for life; or if I feed them "normally" again, will they refuse the food as they are not accustomed to that amount of food??
