In a previous post I stated that I had moved some convict wigglers from their parents to a couple gallon tank. This was a little over a week ago. Well all of them are still living and beginning to swim around fairly easily. They eat crushed flakes 2 or three times a day and are thriving. Question is: I have a 30 gallon tall which only houses a 4" pleco. When can I move the convict fry to this tank? I'm only gonna keep them in there two or three weeks, due to the fact there is about 50 of them. I got some friends who are going to take them off my hands when they find the space. Again, when should I move them to the bigger tank?
