A month ago I had a school of about 20 in a 75g, this being my third batch. Now there are about 12-14 remaining. Every month or so one or 2 of these otherwise seemingly healthy fish will develop these lumps, or simply turn pale with clamped fins[sometimes without any lumps] and die(first 2...

I had been offered what supposedly looked like yellow shrimps and blue velvet. However, the blues have some uncanny markings on their body[actually looks good to me]. I got them real cheap(@ < $1.00 ea or its equivalent in my currency), however the downside is, the seller had no clue if they...

I am thinking of introducing some pond snails procured from fellow-hobbyists to feed the assassins. However I have so far been reluctant since I do not want any other pest to hitch a ride in my tank. Is there any way to ensure no other pests are inadvertently introduced?

I had previously kept some yellows in a 75g planted with amanos and threadfins. Recently I got a 10g and wanted to start a shrimp only tank. Question is, is it possible for shrimp to thrive and multiply if I keep them in a bare bottom tank with maybe lots of java moss, or some moss balls[filter...

My Eheim 2217 sometimes makes a whirring sound even though both the inlet and outlet is completely submerged. Also at times I see air bubbles exuding from the outlet pipe. I checked but there aren't any leaks. Anyone experienced this or knows whats this all about? I'm running the filter 24*7...

I got my second batch of Otos for my 75g a fortnight ago. So far they are all thriving and done a great job cleaning up the glass. Problem is, soon there will not be much algae left for them to munch on. Fearing this I am trying to get them to eat a variety of veggies, problem is they don't seem...

I had been contemplating on buying a pair of straight pinsettes. However, while looking through various options I discovered there are actually 2 types of the equipment. One that is precision tipped[or pointed tip], and the other, that is blunt, or the round tip. Can anyone tell me the...

Hi, I have been keeping a small colony of assassins for some time now. Recently I've come to notice, sometimes a few assassins with either creep up the walls of the tank towards the surface, or simply float to the top, where they will stick their operculum out of the water, languishing in that...

Of many topics on Otos that come up periodically, people[including me] have one question in common. "what species of otos is this?...." or "I've purchased a dozen Otos and some are different than the others?...". I've decided to start a thread on this board, to help identify a particular...

My tank was fine for the last few months until this algae started growing out of nowhere a week ago. No new plants added: ferts- neither increased or reduced dosing- minimum(pps-pro) Co2- 2bps lighting- 3x t5ho photoperiod- currently 7hrs/day water changes- every 10 days Is this clado? Any...

Yesterday I added my NPK to 1 Litre of DI water according to the PPS-pro system. After about 8 hours I see white crystalline precipitate at the bottom of the bottle. I dont know which of the chems(K2SO4, KNO3 or KH2PO4) has not dissolved. Tried heating, shaking -does not work. What do I do now?

I recently purchased some NPK(PPS system) for dosing. I wanted to know is refrigeration necessary for the solution? I am talking 38-42°C(100*107°F).

hi I got 7 serpaes to my 7 week old planted tank 3 days ago. Since the time I got them, they've been hiding in the vegetation and drift. Only today did I see them come out for the first time when the lights were off. However when I switched the lights on, they darted back to their hiding place...

hi everyone, this is pretty much my first post here regarding my new tank cycling. I have already setup my tank about a fortnight ago. However I intend to add fish later, until Im sure the tank is fully cycled. It is a fully planted tank with more species of plants that will come in the...
