Hi,

I noticed yesterday that one of my red dwarf gourami's has developed a white area along the top of its head just before the fin. He seems very active and is eating well, no colour fade. He does go through a rock we have in the tank which is quite a tight squeeze, I wondered was it maybe an abrasion? I have taken photos but not sure how to get them onto post.
We have a 140L tank (L=122cm, D=32cm, H=47cm), we cycled the tank for 8 weeks (fishless) and have had fish in tank for about 7 weeks. We have 2 red/1blue dwarf gourami's, 6 roberti tetra, 6 black phantoms, 3 juvenile blue rainbows and 1 siamese algae eater. We use a fluval 4 plus filter, gravel depth 3cm, soil and gravel, tap water, dechlorinator, daily fertiliser, carbon fertiliser. We have real plants, a couple of rocks with holes, a large piece of bog-wood with some hiding places. Water is changed every weekend 20%, we feed 6 days a week flake and bloodworm on alternate days - only enough they finish in 1 min.
Water parameters: pH = 7.4, Ammonia, Nitrites & nitrates = 0. Temp = 25 - 27oC.

Think I've put all details but if not please let me know.

Any advice would be great,

Janice

It's hard to know for sure without photos, but dwarf gouramis are susceptible to bacterial infections.

There is a viral disease known as "Dwarf Gourami Disease". Is the fish still eating and active?

Here's a guide on how to post photos: http://www.aquahobby.com/board/viewtopic.php?t=14468

By the way, I figure a tank with those dimensions should be closer to 180L capacity, not 140L.
