3 weeks is a long time for fish.. I think you can buy electric feeders at the pet store, ive never used any personally. if you get one,you might want to try it out ahead of time.. and dont put too much food in. remember its better to underfeed them than overfeed them. you dont want to have an ammonia spike while your gone. Weekly feeders can muck up the water pretty well too. and there only ment to last a week. putting 2 in at a time is not a good idea either. this will just cause an ammonia spike. How big is your tank? really the best thing is to have someone come feed them every other day. but if thats not an option, maybe you could possibly take your tank to someone else's house? but other than that.. best of luck. |
