Day 6! One day away from being a week old! 🥰
It's been 6 days since the start of their journey and I'm very happy to say that none of the plecos have passed so far which is one of the highest survival rates I have observed throughout compared to my other batches of pleco fry!
I realised that the key is to allow the fry to stay under the care of the father within the breeding cave until they are just about to fully use up their yolk sacs before manually transferring them into a breeder box! Given that they are extremely fragile in the beginning stages of their lives, they might be overly stressed and may die from shock or physical injuries during the process of transferring them!
Aeration is also important to induce sufficient agitation in the breeder box to ensure that the water body isn't stagnant, and that there is proper circulation and gas exchange for the plecos!
They seemed really healthy and loved the blanched cucumbers yesterday. I will have to think of something else with lesser sugar content for them to consume today though! Fishes also require a balanced diet! :)
Having observed pleco fry development over several batches, I've learned that the initial care stages are absolutely critical for their survival and growth. Allowing the fry to remain under the father’s care within the breeding cave until their yolk sacs are nearly depleted prevents early stress. This step significantly reduces mortalities compared to immediate manual transfer. When the time comes to move the fry, it's essential to handle them gently to avoid shock or injuries as they are extremely fragile at this stage. Maintaining proper water conditions inside the breeder box is another key factor in ensuring their well-being. Continuous aeration creates gentle water movement that mimics natural conditions, preventing stagnation and supporting proper gas exchange. This ensures that the fry receive enough oxygen, which is vital for their development. A balanced diet is just as important as environmental care. While the pleco fry in this batch enjoyed blanched cucumbers—which provide good nutrients—it’s important to rotate their food to avoid excessive sugar intake. Offering a variety of low-sugar vegetables like zucchini, spinach, or peas can help maintain their health and support steady growth. In my experience, a combination of minimal disturbance, optimal water circulation, and thoughtful feeding truly leads to the highest survival rates. Tracking growth daily helps adjust conditions and diet as needed, tailoring care for this delicate early stage. This hands-on, attentive approach to breeding plecos not only boosts survival but fosters healthier, stronger fry ready for their next life phase.
