The Black goldfish can get fairly big at 15 cm, they are also a hefty goldfish. Tank Recommendations for Blackmoor goldfish. Blackmoor is not found naturally in the wild as they are selectively bred fish for the captive environment. Because of this they aren’t exactly beginner fish but are a great way to enter the world of keeping fancy goldfish. Blackmoor just like all fancy goldfish does get fairly sizeable reaching around 15 cm long when fully grown but also do get fairly round.

Unlike some other newer fancy goldfish which are more suitable for tropical conditions, the black moor can be successfully kept all year round in an outdoor pond as long as the pond depth is below any frontlines in colder regions. Ranchu and goldfish in general are great algae eaters and will make a fantastic addition to outdoor ponds as they will readily graze and eat any algae which can proficiently grow in sunny pond conditions. Black Moors also have the classic four-tipped tail also called fantails which look amazing as the fish ages providing these butterfly-like flowing fins. Their jet black colour also makes them an amazing addition to mixed fancy goldfish tanks because of the stark contrast they provide when compared to other goldfish and are also a super active and personality-filled species. most commonly they can develop very contrasting yellow scales on their belly and overall they are fantastic looking goldfish.

Black moors can range in the intensity of their black and as they age other colours may be observed such as mild reds, coppers and yellows. The black moor strain itself is one of the oldest fancy goldfish types dating back to the 1700s in China. Black moors are so unlike the typical orange or gold colour that is associated with goldfish and may even look like a different fish altogether but are easily recognized by the jet black colour and most importantly the large bubbly eyes they have. The tank has been fully cycled for about a year now, and I haven't noticed anything unusual about him either.An age-old classic and a must-have in any goldfish aquarium is the Blackmoor. I've been with this little guy for awhile and I'm very fond of him, so please, any help would be appreciated! Its usually been about 72F but has been at 74-75F. The water has been a little warmer than usual, but only by a couple of degrees. With hard water, again, which he has always been in. The PH was 7.5, which is what is has always been. Its a semi-planted tank, and I do partial water changes weekly and use all the ph balancing and water conditioning chemicals. The two filters are an Aqueon Power Filter 55/75 and a Tetra Whisper EX20 (20 Gallons). The two goldfish get along very well and the other goldfish is doing fine. He is currently in a 55 gallon aquarium with one other fancy gold fish and two small snail. He is usually a happy, active little goldfish. He had an issue with floating at the top of the tank a few days ago, but it seemed to go away after a steady diet of peas. Lately he has been sitting at the bottom of the tank in the corner. I've been very concerned about my little two year old moor.
