JBL ProNovo Spirulina Flakes M - 250ml

JBL ProNovo Spirulina Flakes M - 250ml is an algae-based food for algae-grazing aquarium fish. JBL gives the target fish size as 8 to 20cm. It comes in a 250ml pack.

Key Features

• Plant matter, not protein: grazing fish are built for a low-protein, high-fibre diet and do badly on a meaty staple.
• Spirulina: a blue-green algae used across the aquarium trade as a plant protein and pigment source.
• Prebiotic: JBL adds prebiotic fibre across the ProNovo range.
• Sized for 8 to 20cm fish: JBL works this range out by body length, because mouth size is what decides whether a fish can actually eat a piece.
• 250ml pack: pick a size you will get through in a few months rather than the biggest on the shelf.

How To Feed It

• Feed small amounts two or three times a day rather than one big meal. Fish have very short guts and do better on little and often.
• Give only what is cleared in two or three minutes. Anything still drifting after that will rot in the substrate and push your nitrate up.
• Net out the leftovers. Uneaten food is the usual reason a tank goes cloudy a day or two after feeding.
• A fasting day once a week does healthy adult fish no harm and gives the filter a chance to catch up.

Good To Know

• Overfeeding is behind most cloudy water and high nitrate. The food is rarely the problem; the amount almost always is.
• Keep the tub shut and somewhere cool and dry. Damp gets into fish food easily, and once it does the vitamins go and mould can follow.
• Buy a size you will finish inside a few months. A big tub left open for a year is a false economy.
• Match the piece size to the mouth. Anything a fish cannot swallow gets picked at, dropped and left in the gravel.
• No one food suits every fish in a community tank. A staple plus something that reaches the bottom feeders works better than one food for all.
