I've had tiger barbs for going on two years now and have noticed an unfortunate trend with my group. It seems that the group will all be doing well for a while and then all of a sudden one breaks off from the group and dies shortly their after. This repeats with one or two more (each breaking...

I have a 20 gallon tank that's about 2 years old and my fish seem to have become very lethargic over the past few months. None have died but they're less active and don't respond to food the way that they used to. There has also been a lot of brown algae growing recently. Here are the specs...

I have 20 gallon and 36 gallon planted tanks (the 36 has CO2 and the 20 does not). I've gone back and forth on using/ not using fertilizer with them but had settled on not using it a few months ago. About a month ago I noticed a lack of growth from some plants and started using Tropica Premium...

I have a 36 gallon tank with two opaline gouramis (both males). There has been some aggression between them but nothing too much. Today, I added 6 platys to the tank and the gouramis have been chasing them all around. Any advice as to what I can do? Would it help if I moved one of the gouramis...

I have a tank with eight tiger barbs that are typically very active and school together all of the time. I noticed today that one of them is no longer staying with the group but is instead staying in a corner and not moving much. Is this normal or should I be concerned?

I've been having brown algae grow in my tank at a fairly slow rate for a while now. I've mostly addressed it by scrubbing patches of it off of my leaves/ glass as they arise. The biggest issue I have encountered is with my small-leaved plants (such as s. repens). It's difficult to scrub these...

I recently trimmed a bunch of floating water sprite and cleaned some dead leaves on other plants throughout my tank. Afterwards, I noticed that the ammonia had spiked to 1.0ppm. Was this likely caused by me trimming and cleaning or is there something else I should be concerned about?

I have a 5 gallon tank that has suddenly run into some pH issues. My tap-water's pH is typically a bit low (6.5ish) but the pH usually increases once I add it into the tank to about 7.5 (I assume this is due to the rocks I have in the tank). However, this has not been the case recently. After...

I have a 150 Watt Marineland Precision Heater in my tank that seems to no longer be regulating itself. It continuously heats regardless of the water temperature and my tank has become excessively warm. Has anyone experienced this problem before? Are there any ways to fix the heater or should I...

I did some tank maintenance yesterday where I did about a 40% water change and cleaned a fair bit of green and brown algae (as well as a bit of blue-green algae) out of my tank. As per usual, all of my tiger barbs hid while I was doing so. There was one exception that was swimming in a more open...

Does anyone know of a way to get a shimmer effect in a tank without surface agitation? I would really like to have a shimmering effect in my tank but I run CO2 and don't want to lose any by running a wavemaker. My tank is a 36 gallon bowfront that runs two LED lights.

I have a planed 36 gallon bowfront that has had algae problems since day one (it was initially setup about 9 months ago). Typically, it's a green algae that covers the glass and substrate but more recently there has been a brown algae that coats my plants. I've tried several approaches to stop...

I have a 36 gallon tank with 15 tiger barbs in it with the final 3 having been added last week. Around the same time that these three were added, one of the established barbs started to display some symptoms of illness including pale color, vomiting, and erartic swimming. I thought it might...

Hi Everyone, I've been working to setup a tank for about the past four months. It's been having some issues but I'm not quite sure what's going on. Here are the details: Problems The biggest issue is that I can't seem to keep fish alive. I have 6 tiger barbs currently which is about half of...

Hi All, My pleco had been very healthy until it jumped out of my tank yesterday. I was able to get it back into while it was still alive; however, it moved very lethargically. When I got it back into the tank,other fish started biting at it until it found a hiding spot. When it came out earlier...

Hi Everyone, I've had a 36 gallon bow front since 2008. The tank had been fish only but I recently added 2 plants which don't seem to be doing very well (multiple leaves have fallen off and others are turning brown). I currently have a Fluval Aquasky light which has 2400 L and 3000-25000 K with...

Hi Everyone, I've been looking to add a couple plants to my 36 gallon tank; but, I've been having trouble determining how much lighting I need. I currently have an 18W LED system that generate about 1250 Lumens. Would this be enough for a couple of plants? Thanks!

Hi, I'm a new member on the forum and wanted to introduce myself. I've been keeping a 36 gallon freshwater tank for 5 years. I currently have 2 tetras, 5 gold barbs, 2 gouramis, and 2 corys. I'm also currently preparing to start a 75 gallon freshwater tank. I'm looking forward to being part of...
