The most visually stunning pleco available

The Lemon Blue Eye Longfin Pleco from School of Scape is simply extraordinary. The combination of the brilliant yellow body, the startling blue eyes, and the elongated longfin variety finnage creates a fish that looks almost too beautiful to be real. The fish arrived healthy and has been establishing in my planted tank for two months. Magnificent.

Blue eyes against yellow body – extraordinary combination

The visual combination that makes the Lemon Blue Eye Longfin Pleco so remarkable is the contrast between the vivid yellow body and the striking blue eyes. Most plecos are brown and nondescript. This fish is completely different. The yellow is vivid, the blue eyes are genuinely striking, and the longfin variety adds flowing fins to the combination. School of Scape delivered a healthy juvenile.

Perfect algae cleaner that looks spectacular

Unlike generic algae-eating fish that are functional but dull the Lemon Blue Eye Longfin Pleco is spectacularly beautiful while performing an important ecological role. It rasps algae from glass surfaces and plant leaves throughout the day and the blue eyes scanning the glass surface as it works is charming. School of Scape delivered a healthy active fish that began cleaning algae within hours.

Maximum size of 5 inches makes it suitable for most tanks

One of the practical advantages of the Lemon Blue Eye Longfin Pleco is its manageable maximum size of 4-5 inches. Common plecos reach 18 inches or more and become unsuitable for most home aquariums. This species stays appropriately sized and can be kept permanently in a 30-40 gallon planted tank. School of Scape juvenile arrived at approximately 1.5 inches.

Completely leaves plants alone – planted tank safe

I was concerned about a pleco damaging my aquatic plants but the Lemon Blue Eye Longfin Pleco from School of Scape has not touched a single leaf in two months. It focuses exclusively on algae and biofilm on hard surfaces. This plant-safe behaviour makes it an ideal addition to any planted aquarium that needs algae control without plant damage.

The longfin variety adds elegance to an already beautiful fish

The standard Lemon Blue Eye Pleco is already remarkable but the longfin variety adds an extra dimension of elegance. The extended finnage flows and waves as the fish moves across surfaces and the overall appearance is reminiscent of a dragon. School of Scape delivered a beautiful longfin specimen with well-developed fins and the characteristic vivid yellow and blue eye colouration.

Primarily nocturnal but active during the day too

Lemon Blue Eye Longfin Plecos are primarily nocturnal but the fish from School of Scape has become increasingly active during daytime hours as it has settled in. It is now often visible on the glass or on driftwood during the day which allows me to appreciate its extraordinary appearance regularly. Having driftwood and caves in the tank gives it resting spots. A fish that rewards patient aquarium keeping.

Great driftwood companion – loves resting on wood

Lemon Blue Eye Longfin Plecos love driftwood as both a resting surface and a source of biofilm. My fish from School of Scape immediately claimed the large piece of dark iron wood in my tank as its main territory. The yellow fish against the dark wood looks extraordinary. School of Scape stocks both the pleco and the driftwood which made setting up the ideal habitat very convenient.

Arrived healthy and immediately settled in

The Lemon Blue Eye Longfin Pleco from School of Scape arrived via express shipping in excellent condition. After careful acclimatisation it entered the tank confidently and within hours was already grazing on algae from the aquarium glass. There was no hiding period. School of Scape fish are clearly well-conditioned before shipping. Very pleased.

A conversation piece in any aquarium

Every single person who sees my aquarium for the first time asks about the Lemon Blue Eye Longfin Pleco. The yellow body and blue eyes are so unexpected and striking that the fish commands attention even when stationary on the glass. School of Scape makes this extraordinary species available in Australia at a fair price.

Eats algae wafers enthusiastically

Supplementing the natural algae in my tank with sinking algae wafers has been eagerly adopted by my Lemon Blue Eye Longfin Pleco from School of Scape. At feeding time the fish emerges from its daytime resting spot and consumes the wafer with enthusiasm. Fresh vegetables like blanched zucchini are also accepted readily. School of Scape delivered a healthy fish well-adjusted to captive feeding.

Bristle development on juveniles is already visible

Sub-adult Lemon Blue Eye Longfin Plecos develop the characteristic facial bristles. On my fish from School of Scape the early bristle development is already visible at the corners of the mouth. As males mature these bristles become more pronounced. The yellow body and blue eyes combined with the developing bristles create a uniquely characterful fish.

The most beautiful pleco species in the entire hobby

After keeping several different pleco species over the years I have absolutely no hesitation in saying the Lemon Blue Eye Longfin is the most beautiful of all of them. The vivid yellow body, the striking blue eyes, the flowing longfin finnage, and the developing facial bristles all combine in a fish of extraordinary beauty. School of Scape makes this premium species accessible.
