I have 25 red zebra fry and 3 tiger barbs in a 10 gallon tank. The fry are about 2 months old now. I will be going away for 5 days. Iâ€™m debating whether I should get one of those feeder blocks that should last a few days or just not feed them until I get back. The other option would be to relocate the tank to a friendâ€™s house until I get back. I have automatic feeders for my larger tanks. I know that some people leave their larger fish go for that long without feeding them and everything is fine but I did not know about the fry. I was worried that the fry do not have the larger body mass to sustain them without meals.
