Sera Holiday is a long term staple food for tropical fish in community aquariums.
The unique layered formulation of each tablet delivers a constant supply of high protein food to your fish - even when you're not there to feed them!
The food is rich in protein and becomes soft layer by layer from the outside to the inside, so only the corresponding outer layer is being eaten off. The rest of the tablet remains stable and fresh. The fish are thus well supplied with all essential nutrients for over 1 week.
Overfeeding is virtually impossible since the food becomes soft only slowly and must be worked for by “grazing”. The water is not polluted.
Put 1 tab per each 80 l (21 US gal.) for a week in the aquarium (depends on fish stock).
A few days prior to departure, place a tablet on the aquarium gravel to help your fish become accustom to eating Sera Holiday Food.
On the day of departure, feed your fish the normal quantity of their regular food and place the correct number of Sera Holiday tablets (according to the feeding guide) on an open area of gravel.
Your fish can begin eating from the tablet 24 hours later.
Tablets maintain their freshness for 7 days.
Do not use for surface feeding fish or fish that will not accept dry food e.g. Hatchet Fish.
Complete a partial water change a few days prior to departure and ensure that all water values are within range.
Sera Holiday is the holiday food consisting of carefully manufactured food tablets which is readily accepted by most ornamental fish.
